Drop the unnecessary disk definition and use x86_64 emulator.
For 'qemuxml2argvtest' replace the fake-caps invocation by a 4.2.0
version-locked invocation and add a '_CAPS_LATEST' invocation.
For 'qemuxml2xmltest' convert to use '_CAPS_LATEST' only.
There are no sound-device relevant changes in the output files.
