udev: Use udev.inc and add udevadm to udev pacakge instead of udev-utils

udev: Use udev.inc and add udevadm to udev pacakge instead of udev-utils

* Main purpose of the patch was to fix the problem where udev-utils was
  needed to be in root file system just to get udevadm binary. So this
  binary is moved into udev package instead.

* Use INC_PR for all except udev 151.

* Use udev.inc in all recipes except udev 151.

* All udev recipes built udev_151 and udev_124 runs fine too.

* in udev_151 Add module-init-tools-depmod to RDEPENDS.
