[PATCH xserver] autogen: Set a default subject prefix for patches

[Adam Jackson]

Per discussion at XDC2015, we want this so we can easily distinguish
which module a patch is for. There's no way to set this in the
server-side config, so setting a default at autogen time is about the
best we can do.
