maint: Gnulib module gc
Remove Gnulib modules that coreutils code no longer use directly.
Some of these are used indirectly, but gnulib-tool should do that.
* bootstrap.conf (gnulib_modules): Remove calloc-gnu, cloexec,
getgroups, getpass-gnu, getugroups, getusershell, gnu-mae,
group-member, lchown, mgetgroups, netinet_in, readlink,
realloc-gnu, rename, rpmatch, stpncpy, tzset, wchar-single,
wcswidth.

maint: assume non-rare encodings
* configure.ac (GNULIB_WCHAR_SINGLE_LOCALE): Define.
This can improve performance, while dropping support for
rare encodings on non-GNU platforms. Nowadays these encodings
are typically not worth the hassle.
