VM: Add --results_dir_root option to cros_run_parallel_vm_tests

Browse Source 
This allows the user to specify a custom results directory root. cbuildbot can
be switched to use cros_run_parallel_vm_tests if necessary without any further
changes.

Also create parents directories for user-specified results directory roots in
run_remote_tests.
