Add dependency for external files to the corresponding RepositoryDirectoryValue

Previously we were adding a dependency to the rule itself, however the repository
itself can depends on further dependencies (environment, template files, ...) with
Skylark repositories. Not invalidating when those change was causing weird invalidation
issues that were shown with the invalidation on environment (basically a refetch of
the repository on environment invalidation would not cause an invalidation of the
corresponding package, the next call would not have invalidation of the repository
but would see the change in the build files...).
