[PATCH] mbuto: always display help message

[Sevinj Aghayeva <sevinj.aghayeva@gmail.com>]

Currently, if the user is not root or if fakeroot is not available, no help
message is displayed. Parse the command line, display the help message and then
exit if the user is not root or if fakeroot is not available.
