chromeos: Remove references to UnlockScreenFailed signal.

This looks like it was initially added to handle D-Bus
signals emitted by powerd when we failed to unlock the
screen for some reason, but there are no references to the
signal in either the power manager or session manager source
now, and I can't find any code in Chrome to emit the signal
either.  Code Search doesn't show any references to
"UnlockScreenFailed" outside of the chromium tree and
system_api.

BUG=chromium-os:24003
TEST=manual: still able to lock and unlock the screen; automatic locking on suspend works too
