ossaudio: check for oss support in oss_audio_init
Check whenever the device path (/dev/dsp by default) exists and qemu is allowed to access it. Return NULL if it isn't, so ossaudio will not be used on systems wihtout oss support (increasinly common on modern linux systems). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
