chromite: make gsutil accept a user to create cache dir.
This CL is used for devserver package on DUT calling gsutil in chromite.

cache_dir, to avoid the case that 'root user cannot create cache dir'.
BUG=chromium:698304
TEST=emerge chromite to local moblab DUT, call devserver to provision
it. Ran cros flash ssh://. Ran cbuildbot/run_unittest.
