[oe] [meta-oe][PATCH] lvm2-udevrules: Add ALLOW_EMPTY

[Ovidiu Panait]

When lvm2 is configured without udev feature, the lvm2-udevrules package
is empty, so do_rootfs will fail to install any other packages that
rdepend on it. (e.g. cryptsetup with meta-secure-core layer since commit
https://github.com/jiazhang0/meta-secure-core/commit/afc3939):

..
Problem: conflicting requests
 - nothing provides lvm2-udevrules needed by cryptsetup
..
