[PATCH 1/2] dracut-functions.sh: support for alternative udev dirs - udevaltdirs

[Amadeusz Żołnowski <aidecoe@xxxxxxxxxxxx>]

It is required for Gentoo which moves udev from / to /usr and supports
both /lib/udev and /usr/lib/udev for compatibility with other packages.

Credits go to Alexander Tsoy <alexander@xxxxxxx>.
