[bug#63057] [PATCH core-updates 2/3] installer: Filter out C.UTF-8 from the list of locales.

[Josselin Poiret via Guix-patches via <guix-patches@gnu.org>]

* gnu/installer/locale.scm (supported-locales->locales): Filter out C.UTF-8.  It
doesn't follow the other locales' format, and doesn't have a corresponding
iso639 code.
