util-linux-ng-blkid: proper busybox blkid replacement

/sbin/blkid is provided by both bisybox and util-linux-ng-blkid package,
but at different paths. Busybox version does not accept any options (ignores),
which partially leads to attempted access to /dev/mtdblock0 on OMAP
architecture, which by itself leads to excess error messages from mtd layer
due to different ECC methods (OMAP processor requirement for booting).
If using util-linux-ng-blkid, plus a small patch to udev rules
(http://markmail.org/message/454coplvll4vf3jf) this issue can be fixed.
