lo_mount: check for loop support needs privilege escalation (#437)

Browse Source 
If there is no free loop device, the call of loopsetup -f will create one and return it. For this it needs privilege escalation.
It doesn't need those, if there is already an used device, but that cannot be guaranteed.

Closes #436
