udevd has a nice level of -4, which is inherited by spawned children.
This patch restores the usual level of 0, to help mitigating the effects
of broken processes which consume all the available CPU.

(I don't know the real cause, I'm still investingating it, but the patch
looks like a good idea anyway.)
