When invoking the script with -s, we end up passing a bogus value
to QEMU:

$ ./scripts/qmp/qom-set -s /var/tmp/qmp-sock-exp /machine.accel kvm
{}
$ ./scripts/qmp/qom-get -s /var/tmp/qmp-sock-exp /machine.accel
/var/tmp/qmp-sock-exp

This happens because sys.argv[2] isn't necessarily the command line
argument that holds the value. It is sys.argv[4] when -s was also
passed.

Actually, the code already has a variable to handle that. This patch
simply uses it.
