dashboard: make website be linux-amd64-only, like vulndb

Also make vulndb run linux-amd64-race.
(Everyone should run the race detector!)

Also make mobile run on linux-amd64 trybot.
It already runs on linux-amd64 post-commit.

Also make mobile run on linux-amd64-race trybot.
(Everyone should run the race detector!)

Also run linux-amd64-longtest-race post-commit
on every repo, just like linux-amd64-longtest does.
