qemu: Fix virQEMUCapsCommands formatting

Starting with commit id 'fab9d6e1' the formatting of:

{ "command-name", QEMU_CAPS_NAME },

was altered to:

{ "command-name", QEMU_CAPS_NAME},

and then commit id 'e2b05c9a' altered that to:

{ "command-name", QEMU_CAPS_NAME}

So, let's just fix that up to make things consistent with the
rest of the structures.
