writeback: Allow running tracker-writeback from the source tree
This commit adds a TRACKER_WRITEBACK_MODULES_DIR environment variable which lets us cause tracker-writeback to look for its modules in a custom location. This means it no longer needs to be installed into /usr in order to be used. This is needed to allow running the functional-test suite from the source tree. There is already a similar feature in tracker-extract.
