Several fixes

- set debug level via cmdline
 - set default RW paths needed ALWAYS to boot a working system, even
   with no config files(recovery)
 - Check for loop device before mounting it to avoid duplicated mounts
 - Force overlay and bind arrays to uniqueness
 - Rename OverlayDir to OverlayDirs to better represent the content
