commit 950a90d489 mocked some virCommand handling for the qemu tests,
but we were using that in the test suite to call test-wrap-argv.pl for

Switch the generator code to just use system() instead

I dislike giving up the potential utility of virCommand*() in tests, but
this does fix the problem (without creating the inefficiency of an extra
function in the callstack for every virCommandRun() call by every
libvirtd in the world). So ACK unless someone has a better idea /
different opinion. (But there's one thing to fix, noted below).
(if this was in a binary run outside the build environment, I would NACK
use of system(), but since it's only used by a test...)

For that matter, cmd would be NULL if virAsprintf failed, so all that's
really needed here is a "return -1;", meaning that the cleanup label can
also be removed.
