cmd/coordinator: make contended gomote create request cancel post-submit build
If somebody wants to "gomote create" a reverse buildlet that's busy
doing a post-submit build, the coordinator tries to find an active
non-trybot build and call (*buildStatus).cancelBuild() on it, to make
it clean up and return itself to the coordinator, so the scheduler
will get it soon and give it to the gomote user.
Fixes golang/go#35714
