Expose PID of current process as a standard upstart environment variable

When writing post-start / *stop jobs, it is often useful to have the PID of the currently running job.
Having upstart export the PID it is tracking would be nice as it reduces the repetition of "status <job> | pgrep [...]" like constructs.
