[libvirt PATCH 2/2] testsutilsqemu: check return value of virQEMUCapsNewCopy

[Ján Tomko <jtomko@xxxxxxxxxx>]

While for virQEMUCapsNew this should not be needed
(the possible failures in VIR_CLASS_NEW are only hit
 on bad API usage which we don't do here),
virQEMUCapsNewCopy calls into many other functions,
some of which actually fail.

Check the return value of both.
