SLE15: genimage fixes

Browse Source 
- Mount /sys and /proc
- needed for newer versions of the SLE permissions RPM. See: 2d0ef5d55b
- Create /sys to have /sys/kernel/fscaps. Fixes: "Warning: running kernel does not support fscaps"
- Fix permissions of /dev devices
- Make sure /sys and /proc are unmounted everytime
