You're right, all envvars copied in qemudBuildCommandLine should be
unset or set to known values in this testcase to make sure the test is
not affected by the actual envvar values.
But SDL_VIDEODRIVER is not copied in qemudBuildCommandLine and
QEMU_AUDIO_DRV is copied but not unset in the test.
I suggest the attached patch.

Subject: [PATCH] Unset copied environment variables in qemuxml2argvtest
The test expected all environment variables copied in qemudBuildCommandLine
to have known values. So all of them have to be either set to a known value
or be unset. SDL_VIDEODRIVER and QEMU_AUDIO_DRV are not handled at all but
should be handled. Unset both, otherwise the test will fail if they are set
in the testing environment.
* src/qemu/qemu_conf.c: add a comment about copied environment variables
and qemuxml2argvtest
* tests/qemuxml2argvtest.c: unset SDL_VIDEODRIVER and QEMU_AUDIO_DRV
