platform/dev: add 'chromite' import & process id handling.
Current devserver does not have 'chromite' dependency. Also, in real devserver,
the cros_update process's id is different from the shell id, and the
path of 'stateful_update' is different from that in drone/shard.
This CL:
1. add 'chromite' import
2. pass the 'devserver directory' to ChromiumOSUpdater.
3. Create a process group before newing the cros_update process. Use the
process group id as the unique file identifier. Kill the whole process group if
neccessary.
BUG=chromium:636467
TEST=local autotest to trigger repair & provision.
real test in devserver chromeos4-devserver2.
