gnu: glibc-utf8-locales: Hide the package.

This package has a long history of confusing users, due to containing only a
small, arbitrary subset of UTF-8 locales.

* gnu/packages/base.scm (glibc-utf8-locales): Define as a hidden package.
* doc/guix.texi (Application Setup): Do not mention glibc-utf8-locales.
Instead, provide an example for defining a custom locales package.

 Note that the @code{glibc-locales} package contains data for all the
 locales supported by the GNU@tie{}libc and weighs in at around
-917@tie{}MiB@.  Alternatively, the @code{glibc-utf8-locales} is smaller but
-limited to a few UTF-8 locales.

+reduced down to about 213@tie{}MiB with store deduplication and further

+locales package via the @code{make-glibc-utf8-locales} procedure from
+the @code{(gnu packages base)} module.  The following example defines a
