Force utf8 locale in all migrid services (#80)

Reuse explicit `LANG` locale setup from `apache-minimal` service helper
in `migrid` init script in order to have consistent sane locale in all
`migrid` services. This is mainly in relation to the encoding issues we
noticed with exotic characters in the `MiGserver.conf` when implicitly
loaded and parsed as ascii in the sftpsubsys PAM module in containers.

This PR should obsolete ucphhpc/migrid-sync#177
.
