Use :language command to force C locale

Browse Source 
In non-Windows environments, the gpg command is prepended with “LANG=C
LC_ALL=C” to ensure gpg's output is consistent to allow for parsing the
information.  However, that doesn't work in Windows and won't
necessarily work if we ever remove the code forcing use of /bin/sh.

Since Vim already knows how to influence the environment, use its
“:language message …” command to set/restore the locale before/after
running the gpg command.
