empathy: find gsettings schemas, enable in gnome3, disable parallel build

Enabling by default on gnome3 as now it's possible to create and use
accounts (tested with telepathy_gabble and gtalk).

At this time, empathy x86-64 fails to build on hydra but I'm unable
to reproduce. Therefore, try disabling the parallel build.

Fix hydra UID

The style for IDs dictates that groups/users should have the same ID -
so if a user doesn't have a group or vice versa, then we should skip
that ID.

In this case, we had already assigned grsecurity GID 121, but I
accidentally also assigned Hydra UID 121. Instead, let's assign Hydra
UID 122. And also assign a GID (122) as well.

Luckily nobody was depending on this yet (except me).
