qemumonitorjsontest: Resolve resource leaks found by Valgrind

The 'package' string returned by qemuMonitorGetVersion() needs to
be VIR_FREE()'d.

testQemuMonitorJSONGetMachines(), testQemuMonitorJSONGetCPUDefinitions(),
and testQemuMonitorJSONGetCommands() did not VIR_FREE() the array and
array elements allocated by their respective qemuMonitorGet* routines.
