kustomize: Update to 4.5.7

Changes:
4.5.7
-----
Due to an oversight, kustomize v4.5.6 has the golang testing library
compiled in unnecessarily. This is a rerelease with the same
functionality, but without the unnecessary additional library compiled
in.

4.5.6
-----
Due to an oversight, kustomize v4.5.6 has the golang testing library
compiled in unnecessarily. It is advised that you upgrade to v4.5.7,
which doesn't have the testing library compiled in.

4.5.5
-----
This release is expected to have significant performance improvements
for a good portion of inputs, due to #4568.

4.5.4
-----
Dependencies updates.

4.5.3
-----
Misc enhancements and bug fixes.

4.5.2
-----
Bug fix release.

4.5.1
-----
Known issues:
 - kubernetes-sigs/kustomize#4455
   A regression, some HTTP urls are not working properly.

4.5.0
-----
 - This release contains a regression in the legacy sort order. Those
   using the legacy sort, i.e. `kustomize build` with `--reorder` unset
   or explicitly set to `legacy`, are advised to skip this release.
   kubernetes-sigs/kustomize#4388
 - kubernetes-sigs/kustomize#4455
   Another regression, some HTTP urls are not working properly.

 - New field in kustomization, `buildMetadata`.
 - New command `kustomize edit add buildmetadata`
 - Refactor the PrefixSuffixTransformer into separate prefix- and
   suffix transformers, enabling the user to use the PrefixTransformer or
   SuffixTransformer individually in the transformers field.
 - `kustomize build ...` now completes file paths on ZSH.
 - New command `kustomize edit add generator` (kubernetes-sigs/kustomize#4361)

 - Deprecate enable-managedby-label flag in favor of a field

4.4.1
------
Bug fix release.

4.4.0
-----
The headline feature of this release is improved support for YAML
anchors and aliases, which will be expanded by default as of this
version.

Additional features and fixes include:
- Added length check on originalFields of kustomizationFile to prevent
  panic when kustomization file began with a comment(or a blank line)
  followed by a document separator

4.3.0
-----
Misc bug fixes and enhancements.

4.2.0
-----
New experimental command to automatically migrate `vars` to
`replacements`: `kustomize edit fix —vars`. For details, run `kustomize
edit fix -h`. Warning: converting `vars` to `replacements` will
potentially overwrite many resource files and in rare scenarios may not
produce the same output when `kustomize build` is run. We recommend
doing this in a clean git repository where the change is easy to undo.

4.1.3
-----
* New experimental ReplacementTransformer, docs on the way:
  kubernetes-sigs/cli-experimental#158
  This will replace the `vars` feature.
* Allow pulls of openapi data from live API servers (openapi fetch command).
* Remote git urls can specify a timeout parameter.
* More examples of helm usage.
* Speed up cluster-scoped type checks.
* API changes towards 1.0
  - `Gvk` and `Resid` types moved to kyaml
  - `Resource` now inlines `RNode` rather than delegating to it
  - `Resmap` now accepts an `kio.Filter` visitor (that can change the ResMap size).
