Remove nonexistent bots from mb_config.pyl

I noticed that I forgot to remove android_unswarmed_n5_rel from mb_config.pyl
in https://chromium-review.googlesource.com/c/chromium/src/+/1135556, so I
tried to write some code to check that all bots referenced in mb_config.pyl
actually exist now that the bot inventory exists src-side.

I couldn't get that to work reliably, but I manually went through the list
my code produced and removed the bots that appear to really not exist according
to cs.chromium.org.
