If you package sudo within your snap snapcraft will strip the necessary
suid bit from it so it wont work anymore. Only way to use sudo is to use
the one from the core snap.

We should fix this so that a sudo <snap-binary> works rather than
putting sudo in a snap or use it from there. You could also check in
your binary if its started as root and if not abort.
