Fix several problems in linux_find_root_device 'stat' returns the major and minor numbers in hexadecimal, while 'mountpoint' returns them in decimal; convert the ones from 'stat' so comparison actually work. Rename variables to reflect better the difference between the DEVICE representation (major:minor) and the NODE representation (a path of a file under /dev). Finally fix the invocation of linux_find_root_device as well.
Remove the debian/ dir from the master branch
