cros_run_bvt: Tweak for labqual.

Dangerous tweak to address a gap in labqual.

BUG=b:269503867
TEST=confirmed that "./cros_run_bvt --board=atlas --labqual --debug \
127.0.0.1" generates an error (no servo type specificed),

confirmed that "./cros_run_bvt --board=atlas --debug" matches the
behavior of the previous version of the script (errors with "Must \
specify exactly one DUT",

confirmed that "./cros_run_bvt --board=atlas --labqual \
--servo_type=servo_v4_with_servo_micro --debug 127.0.0.1" echos a
dut-control command that executes successfully,

confirmed that "./cros_run_bvt --board=nami --labqual \
--servo_type=servo_v4_with_servo_micro_foo $LOCAL_DUT_IP" fails with a
servo type mismatch,

confirmed that "./cros_run_bvt --board=nami --labqual \
--servo_type=servo_v4_with_servo_micro $LOCAL_DUT_IP" executed and
passed the autotest and launched the tast tests (which looked to fail
for an unrelated reason).
