set_lsb_release: Set some fields dynamically from the base profile

Browse Source 
This leverages the branding eclass that was recently added to Gentoo.

Since originally preparing this commit, these fields were added to our
make.conf, but setting them in the profile is more versatile, allowing
for downstreams.
