Jobs that asked for lux-build-amd64 name the fleet with self-hosted

The fleet mints a runner only for a job that names self-hosted or a
linux-<arch> label. A job asking for lux-build-amd64 alone was never given
one, and it still matched runners minted for other jobs that named
[self-hosted, lux-build-amd64], so it took theirs and left them queued.
