REVISION SUMMARY
  As tmpfs mounts are more widely used for shared memory in browsers like Chromium and Firefox, there is a need for more and more space in such filesystems, with grave circumstances when the space is exhausted - it causes instability, crashes or black display in both of these browsers. Given this importance, I suggest tmpfs should not be blacklisted from disk space reporting in ksysguardd. Because tmpfs "devices" don't start with a /, it is needed to obviate the test for "real" device names as well.

TEST PLAN
  Open ksysguard
   Check that sensor Disk Space/dev/shm/... is there
   Check that it shows partly full when you have firefox running
