Makefile: use fakeroot for tar-ing rootfs

Browse Source 
When tar-ing the rootfs, the permissions preserved are from the worker
process. This is not the intended behavior, as we want to preserve the
permissions of the root user to most of the files. Use fakeroot during
the tar process to automagically map the uid of the user to that of
root's.

Fixes #22
