[bitbake-devel] [PATCH] fetch2/git: always use premirror first if update is required

[Pascal Bach]

When an update of the local copy is required always try to fetch the update
from a premirror first.
The premirror should always have precedence over the upstream repository
as updating from there might not work if BB_FETCH_PREMIRRORONLY,
BB_NO_NBB_ALLOWED_NETWORKS or BB_NO_NETWORK is set.

This also gets rid of the special case for BB_FETCH_PREMIRRORONLY.
