x/build/cmd/gomote: put14 reports "unknown builder"

$ gomote create openbsd-386-gce56
$ gomote push user-austin-openbsd-386-gce56-0
$ gomote put14 user-austin-openbsd-386-gce56-0
Error running put14: unknown builder "user-austin-openbsd-386-gce56-0"

I think namedConfig in list.go hasn't kept up with the user-x-builder-n notation, since it looks for a build config whose name is a prefix of the given buildlet name. Simply changing HasPrefix to Contains works for my case, but feels like an ugly solution.

Thanks for the report.

I forgot about the put14 command when we changed the auth. FWIW, put14 isn't very useful, since push does it for you anyway. I think we've made the decision to just nuke the old auth mode and old user-x-builder-n notation entirely (which was never finished anyway), and use the new proxy-via-coordinator style. That will simplify the gomote code. I'll use this bug for that.

It looked like this wasn't working because it also depended on namedConfig.
