bug#27375: Kodi tests take too long

[Ludovic Courtès]

The ‘kodi-test’ program used during the test phase of Kodi takes quite a
bit of time, apparently spent scanning for /dev nodes that it won’t find
and waiting for them to show up, which never happens:

Probably that’s something done by alsa-lib.  It would be good to disable
it though, because currently it takes 14937 seconds (more than 4
