update_engine: Let "power" user query update status.
Change update_engine's D-Bus configuration to allow the
"power" user (used by powerd) to query the update status.
powerd already listens for signals announcing update state
changes, but it also ought to query the current status if it
gets restarted for some reason.
It also removes some "deny" directives that are apparently
undesirable, as "deny" is already the default (see
http://crbug.com/219054).
BUG=none
TEST=confirmed that powerd is able to query the update
status after being restarted
