UBUNTU: [Debian] dkms-build -- use fakeroot if not running as root

BugLink: https://bugs.launchpad.net/bugs/1930713
Some dkms builds require running as root, or at least the illusion of
doing so. However we need to do dkms builds before deleting the
flavour build directory in order to sign the modules, and this may
happen without fakeroot. Detect whether or not dkms-build has been
invoked as root, and if not use fakeroot to do the dkms build.
