[PATCH 12/17] tests/filesystem: improve fsnotify check and preload loop module

[Christian Göttsche <cgoettsche@xxxxxxxxxxxxx>]

From: Christian Göttsche <cgzones@xxxxxxxxxxxxxx>

fsnotify support might be missing from the running kernel.

Pre-load the loop module to ensure creating a loop device succeeds.
