[proaudio] lash fails with -j > 1 plus lash-0.5.4 overlays pylash

[Federico Ferri <xaero@xxxxxxxxx>]

just upgraded to lash-0.5.4 (first I had to use -j1, otherwise it would 
fail - see bug http://bugs.gentoo.org/show_bug.cgi?id=214234)

plus: lash got a file collision with pylash

it seems that now lash provides also pylash, so having a separate ebuild 
for it is useless.

just I had to remove pylash, but jack_mixer was depending on it
