sysctl kern.proc.cwd has been added in r274167 [1].
This patch utilizes the new sysctl to obtain the current working directory of
given process which could save a lot of overhead over kern.proc.filedesc if
the given proc has a lot of open fds.
The patch is against tmux-1.9a [2].
This job is done as part of JuniorJobs [3].
