Unload USB controllers drivers in USB VM before going to sleep

Browse Source 
Many USB controllers doesn't play nice with suspend when attached to PV
domain, so unload those drivers by default. This is just a configuration
file, so user is free to change this setting if his/shes particular
controller doesn't have such problem.

Fixes QubesOS/qubes-issues#1565
