Allow user to turn OSC 7 off

Currently weltschmerz prefers working directory information obtained
from OSC 7 to that from procfs. If a user has not configured their shell
to emit OSC 7 escapes, the OSC 7 path may be out of date. Additionally
some users want only their shell to change the terminal's conception of
working directory, which is a behaviour better matched by the procfs
based working directory detection.

This change allows OSC 7 based working directory detection to be turned
off. The default remains to check OSC 7 first and then fall back to
procfs if there is not valid local path set with OSC 7.

The reason for turning OSC 7 off entirely instead of inverting the order
procfs and OSC 7 are checked in is that procfs based detection should
never fail under normal usage on systems that support it.
