bitbake.conf: drop FETCHCMD, GITDIR, etc fetcher over-rides

This completes cleanup originally proposed in 2012:

  http://lists.openembedded.org/pipermail/openembedded-core/2012-July/064224.html

Current versions of bitbake have "sane" default fetcher commands
so it's no longer necessary for bitbake.conf to over-ride them.
