fix: retain symlinks added to zip archives

[orirawlings]

fixes #3584

When following the reproduction steps in #3584 I now get the following contents for the zip archive:

$ goreleaser --snapshot --skip-publish
...
$ (mkdir thezip && cd thezip && unzip ../dist/test_0.0.0-SNAPSHOT-none_darwin_amd64.zip) && ls -lR thezip
Archive:  ../dist/test_0.0.0-SNAPSHOT-none_darwin_amd64.zip
  inflating: a/x                     -> ../x 
  inflating: a/x2                    -> x 
  inflating: x                       
  inflating: test                    
finishing deferred symbolic links:
  a/x                    -> ../x
  a/x2                   -> x

-rw-r--r--  1 orawlings  staff       2 Nov 22 15:32 x

thezip/a:

lrwxr-xr-x  1 orawlings  staff  1 Nov 22 16:19 x2 -> x

I'm using goreleaser for a project that packages multiple binaries in zip archives. We also include symlinks within the zip archives to give some of the binaries an alternate (usually shorter) spelling so they are easier to invoke on the command line.

This brings the zip archive behavior regarding symlinks in line with tar.gz and tar archives.
