chromeos: Don't override suspend-on-lid-closed.

chromeos: Don't override suspend-on-lid-closed.

This prevents PowerStateOverride::BLOCK_SYSTEM_SUSPEND,
which is used while the system is uploading or downloading
files or playing web audio, from setting the power manager's
disable_lid_suspend override.  This override used to be
unimplemented in powerd, but it works now, and we don't want
the system to stay awake after the lid is closed.

It also renames PowerManagerClient::DISABLE_IDLE_LID_SUSPEND
to DISABLE_LID_SUSPEND; it doesn't have anything to do with
idleness.
