a) Print a warning message "Copying binaries into the pbuilder chroot
and running them there may not work!" if 'file $SCRIPT' returns
something containing "binary".

b) add a --nocopy (or choose a better name) flag so that
       sudo pbuilder execute --nocopy -- /bin/echo hello world
will execute the binary found inside the chroot.
Deriving some automatism to detect the users intentions ('copy and
execute' or 'just execute what's in the chroot') will be hard and
more confusing.
