While investigating bug 1396845 I triggered a lot of rusttest builds on try pushes. I would hit occasional intermittent failures on things like the xpcshell selftests, which makes me realize that we probably shouldn't be running all of those tests on rusttest builds. We already run the rest of `make check` on normal builds, rusttest builds shouldn't waste time on those.

There are a few ways we could go about this. The most straightforward might be to add a new mozharness action that just runs the Rust tests, and then change the rusttest mozharness configs to use that and not `check-test`:

I think the simplest way to fix this would be to make something like `mach test rusttests` work, add a mozharness step to run that instead, and then change the rusttest mozharness configs to run that step instead of check-test.

Assuming it sticks, bug 1505072 will take care of this.
