[PATCH gnumach] CI: Email failures to commit-hurd

This will email gzipped error logs to commit-hurd AT gnu.org from any
forgejo instance set up as a mirror.  This is facilitated by
not specifying any domain or user specific configuration, but to
execute the mailing code path, the repository must be called "gnumach"
and the branch that was synced be "master".
If the mail command is not configured in the CI, it will simply fail
to send mail and the failing test will not be reported.
Since there is only one instance currently set up, we won't get
duplicated reports.
