[Buildroot] [git commit branch/2019.02.x] package/lvm2: install udev rules

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=402c16687f99e42d334ee45305e0231ad0aff6bd
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.02.x

Without the device-mapper udev rules, dm devices will not get a proper
symlink like /dev/disk/by-label/LABEL, which in turn causes fstab
LABEL= mounts to fails.

And by extension causes shenanigans with systemd, where it will
unmount a manually mounted disk because it can't resolve the label.
