[PATCH 2/2] fetch2: Unify BB_FETCH_PREMIRRORONLY

[Robert Yang <liezhi.yang@windriver.com>]

The fetch2/__init__.py checks whether "BB_FETCH_PREMIRRORONLY" == "1", but
fetch2/git.py and hg.py checks whether it is None, this makes it discontinuous,
and BB_FETCH_PREMIRRORONLY = "0" doens't work as expected in the later case,
so unify it to the previous one. (As BB_NO_NETWORK does).
