Move remaining CrOS CQ bots to tryserver.chromium.chromiumos.

This moves chromeos-daisy-rel and linux-chromeos-rel from 50%
experiments to full members of the CQ, and removes
chromeos_daisy_chromium_compile_only_ng and
linux_chromium_chromeos_rel_ng (which are on tryserver.chromium.linux)
from the CQ.
