libqtest: check for g_setenv() failure
g_setenv() can fail; check for it when starting a QEMU process
when we set the QEMU_AUDIO_DRV environment variable.
Because this happens after fork() reporting an exact message
via printf() is a bad idea; just exit(1), as we already do
for the case of execlp() failure.
Fixes: Coverity CID 1460117
