[bodhi] Bodhi critical path updates policy adjustment

[Luke Macken]

FESCo recently made an adjustment to the updates policy to no longer require
proventester karma for a critical path update to be deemed as stable.

Critical path updates will now require just one regular +1 karma vote during
the pre-beta phase and two regular +1 karma votes in other phases to be pushed
to the stable updates repo. Anonymous karma is not taken into account.

This policy change has been implemented and deployed to production with Bodhi
v0.8.6.
