Update crosperf to run telemetry test via autotest.

This updates crosperf to recognize the suite 'telemetry_Crosperf',
which allows users to run telemetry performance tests via test_that
and the telemetry_Crosperf autotest.  This won't be usable in general until
CL 168491 (the telemetry_Crosperf CL) gets committed.

BUG=None
TEST=Invoked telemetry tests using this change.

Note: Profilers don't quite work properly with telemetry_Crosperf yet,
but everything else does.
