CPack unify component/monolithic package symlink handling

Non component package generation was recursing through
symlinks while monolithic package generation did not.
This was causing component archive packages to contain
both symlink and a directory with the same name on the
same level if symlink contained files which caused errors
during extraction of such packages.

Closes #16051
