Peter Krempa 4865dd673d qemu*xml2*test: Cache capabilities between tests
Invoking the XML parser every time is quite expensive. Since we have a
deep copy function for 'virQEMUCapsPtr' object, we can cache the parsed
results lazily.

This brings significant speedup to qemuxml2argvtest:

real	0m2.234s
user	0m2.140s
sys	0m0.089s

vs.

real	0m1.161s
user	0m1.087s
sys	0m0.072s

qemuxml2xmltest benefits too:

real	0m0.879s
user	0m0.801s
sys	0m0.071s

vs.

real	0m0.466s
user	0m0.424s
sys	0m0.040s
