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

[Marko Katić]

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.
This can break do_rootfs stages when building images
that depend on udev since we have RRECOMMENDS += udev-utils.
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.
