Remove broken command line option -balloon

It clashes with upstream's -balloon.

Crept in with -vmchannel in commit af595fab.  Originally came from
qemu-kvm, but is long gone there.  Doesn't work, because commit
af595fab failed to put it in qemu_options[] (looks like a conflict
resolution accident).
