qemu: capabilities: Remove support for downstream-only QMP monitor backport 

Some distros (see diff) chose to backport QMP support rather than rebase
to newer version of qemu. As a hack they added the string 'libvirt' to
the qemu -help output. Remove this as downstream-only hacks should be
carried by downstream and not litter upstream.

This effectively reverts commit ff88cd5905
