busybox: update mdev.conf
busybox 1.21.1 's mdev has changed the way the device's name is
reported so now we get input/event0 instead of event0.
I think this commit is responsible of this new behaviour :

c3cf1e30a3022453311a7e9fe11d94c7a381640e
Update mdev.conf according to this behaviour so that sound
and input devices are correctly populated (and now
/etc/mdev/find-touchscreen.sh is executed).
Tested on an arm board.
