KB-H053 INVALID SYMLINKS: actually breaks valid symlinks

[SpaceIm]

Without this hook installed, I can build and install libressl (https://github.com/conan-io/conan-center-index/pull/2933).

conan create . libressl/2.9.2@

Symlinks are correct:

~/.conan/data/libressl/2.9.2/_/_/package/2af715f34a7c8c2aeae57b25be0a52c4110dc502/lib$ ll

If this hook is installed, the same recipe breaks at installation time:

conan create . libressl/2.9.2@

[HOOK - conan-center.py] post_package(): ERROR: [INVALID SYMLINKS (KB-H053)] There are symlinks in the package pointing outside the package_folder. You can use 'tools.fix_symlinks(self)' to fix some of these symlinks. (https://github.com/conan-io/conan-center-index/blob/master/docs/error_knowledge_base.md#KB-H053)

Then I see that symlinks have been modified (libtls.so has been removed, and others modified but are completly broken), probably by this hook I guess:

So I suppose that this hook is buggy, but also intrusive which is worse.
