let each RemoteShellCommand gets its own .env dictionary

	* buildbot/process/step.py (RemoteShellCommand.__init__): let each
	RemoteShellCommand gets its own .env dictionary, so that code in
	start() doesn't mutate the original. I think this should fix the
	step_twisted.Trial problem where multiple identical components
	kept getting added to PYTHONPATH= over and over again.
