After removal of git server in f3dc178f,
no need for mod_cgid anymore.

Also, the mod_cgid was reporting an error because ScriptSock was not set
so the socket file was created in the software compilation folder:

[cgid:error] [pid 109996:tid 139713924945728] (13)Permission denied: AH01243: Couldn't bind unix domain socket /srv/slapgrid/slappart71/srv/runner/shared/apache/81977b7512b75d38df008fc5ede74d94/logs/cgisock.105061
