Remove "nacl-lucid64_validator_opt" from the list of default trybots

nacl-lucid64_validator_opt takes 1.5 hours to run.  This is a big
waste of limited trybot resources given that most changes do not touch
the x86 validators, so there's no need to test the entire nexe corpus
against them.

In comparison, "nacl-lucid64_glibc_opt" takes only 18 minutes to run.

If you're making an x86 validator change, please manually specify
"nacl-lucid64_validator_opt".
