Support live ebuilds through portage_srcrepo_t 

Portage supports the notion of "live ebuilds", which are packages that, when
installed, update a repository checkout on a specific location. This means
that a few portage-related domains need to have manage_* privileges on that
location whereas they usually have much more limited rights (when live
ebuilds aren't used).

To support live ebuilds, we introduce another label called portage_srcrepo_t
for those specific locations where the "higher" privileges are needed for,
and grant the proper permissions on the compile domains (like
portage_sandbox_t) to manage the checkouts.
