[OE-core] [PATCH] [OE-CORE] udev: make sure udev-utils package always contains udevadm

[dromede at gmail.com]

From: Marko Katic <dromede at gmail.com>

Default installation path of udevadm was changed
from ${base_sbindir} to ${bindir} in udev v176.

Also, udevinfo and udevtest no longer exist in
current (v182) udev sources.

This can break udev-utils packaging since udev-utils
package expects udevadm only in ${base_sbindir}.
And since udevinfo and udevtest no longer exist in
current udev versions, udev-utils could be empty
and thus will not be created.

We should also make sure that udevadm stays in udev-utils
since it might be needed for other packages i.e, busybox
and mdev.

Udev.inc should support all versions of udev. This patch
makes udevadm always available in udev-utils package and
it also makes sure that udevadm is available in both
${base_sbindir} and ${bindir} paths.
