Revert "coreutils: split out coreutils-getlimits"

This reverts commit 149584beef1e1b28a4e51f40515204e7edaa9d1f.

The coreutils-getlimits package is no longer needed since findutils-ptest
now uses its own getlimits implementation. This improves modularity and
makes it easier to use alternative coreutils implementations via PREFERRED_PROVIDER
(e.g. uutils-coreutils recipe in meta-openembedded).
