qapi: add 'query-target' command to return target arch
Add a 'query-target' QAPI command to allow management applications
to determine what target architecture a QEMU binary is emulating
without having to parse the binary name or -help output
$ qmp-shell -p /tmp/qemu
(QEMU) query-target
{ u'return': { u'arch': u'x86_64' }}
