Bug 1572327 - Don't record sccache stats in perfherder per instance type. r=nalexander

Build metrics where the instance type matters, like build times, are
important to keep track of per instance type, but sccache stats are hit
rates, number of non-cacheable requests, and number of write errors to
the cache, none of which are dependent on the instance type.
