functional-tests: Initial test of removable media handling
Removable media indexing is hard to test and the relevant tracker-miner-fs codepaths are dusty at best.
As first stage of cleaning them up, this MR adds infrastructure to simulate removable devices by injecting a GIO module with a fake volume monitor that we can control over D-Bus, along with a simple set of tests.
Fixes #191 (closed)
