git: drop privileges for gc and merge (bug 669496)

Use portage.process.spawn (with new cwd parameter) and self.spawn_kwargs
to drop privileges for git gc and merge commands.

Fixes: 3cd8cf93abb6 ("GitSync: abort checkout for signature problem (bug 660372)")
Fixes: 903c4b1a6768 ("GitSync: support sync-depth (bug 552814)")
Bug: https://bugs.gentoo.org/669496
