Quit running telemetry_Benchmarks on battery power.

When running benchmarks on battery power, failures could leave the
DUT on battery for an extended time, causing the DUT to fail when
the battery drained.  The battery statistics aren't important enough
to fix the problem, so we're disabling running on battery instead.
