change the value of audio_prinfo.seek from u_long to u_int before it causes

too much damange.  everything else here is the same in a 64bit vs. 32bit
world, so keep it all simple.  the alpha was the only port to have any real
affect for this, and it only very recently begun to support some audio
devices so it doesn't really apply here.  1.3/alpha did not support audio..
