[COREUTILS 1/2] build: updated gnulib acl handling

[Andreas Gruenbacher]

This changes how ls checks for acls on Linux (it no longer requires
libacl) and rewrites how acls are set and copied between files.

* gnulib: Update to latest.
* gl/lib/tempname.c.diff: Adjust for gnulib changes.
* gl/lib/tempname.h.diff: Likewise.
* src/local.mk (src_ls_LDADD):  Only link with the libraries needed by
file_has_acl().
