git-download: Set locale to deal with Unicode in git metadata.

Without this the git-fetch GEXP is run in an environment that uses ASCII
character encoding when strings are crossing the Guile - C boundary.  It means
that e.g. tag names that have Unicode chars in them will cause problems,
e.g. when walking and deleting the .git directory.

An example in the wild: https://github.com/klauspost/pgzip/tags

Fixes <https://issues.guix.gnu.org/54893>.

* guix/git-download.scm (git-fetch): Call 'setenv' and 'setlocale' to
set it to en_US.utf8.
* gnu/packages/commencement.scm (glibc-utf8-locales-final): Make public.
Add 'properties' field.
