tests/cache-restore: Do not look for dependency files outside data

When the default dependency path is used for cache distributors, they
are looking for the dependency file in the project's root (including the
source code), which leads to tests taking a significant amount of time,
especially on Windows runners.  We thus hit sporadic test failures.

Change the test cases such that dependency files are always searched for
inside of `__tests__/data`, ignoring the rest of the project.
