crosperf: Update default_remotes to new DUTs

DUTs have been moved to different rows and racks. This updates the
default_remotes accordingly.

These devices are chosen by checking the swarming dimension setting
"label-pool=toolchain".

Additionally, this removes Lulu machines as they are no longer in
the toolchain pool.
