[crosutils] Remove --use_emerged from cros_run_parallel_vm_tests

Browse Source 
cros_run_parallel_vm_tests doesn't work unless you pass --use_emerged; there must be some underlying issue with trying to perform multiple run_remote_tests commands at the same time, even on different VMs.  So, remove the option and force --use_emerged on the calls to cros_run_vm_test.

BUG=8544
TEST=run two tests in parallel with cros_run_parallel_vm_tests and see that they both complete.
