chown is a close superset of chgrp functionality, so merge sources to avoid unwanted divergence in future. This removes about 300 lines in chgrp.c * build-aux/gen-single-binary.sh: Generate new rules for chgrp. * cfg.mk: Exclude new wrappers. * po/POTFILES.in: Remove chgrp.c * src/chgrp.c: Remove. * src/chown-chgrp.c: New wrapper. * src/chown-chown.c: Likewise. * src/chown.c (main): Prepend ':' for chgrp(1). * src/chown.h: Define both operating modes. (usage): Adjust depending on utility being called. * src/coreutils-chgrp.c: Likewise. * src/local.mk: Reference new wrappers.
