Repeatr fails without modprobe but doesn't need it

[tazjin]

Basically this:

INFO[03-17|13:47:05] Input 3/3 ready 
panic: gosh: command not found: "modprobe" [recovered]
	panic: gosh: command not found: "modprobe" [recovered]
	panic: gosh: command not found: "modprobe"

It seems that repeatr attempts to load the AUFS kernel module, but if modprobe is present and AUFS isn't it falls back to to "slow fs assembly system" anyways. That fallback should probably also happen if modprobe isn't there.

WARN: using slow fs assembly system: install AUFS to use faster systems.
