fix(lvm): restore setting LVM_MD_PV_ACTIVATED 
The 69-dm-lvm-metad.rules udev rule has been removed from
the initrd, because it's been dropped by recent upstream
lvm versions, and it never performed any primary function
within the initrd.  But, it did have the job of setting
LVM_MD_PV_ACTIVATED=1 for active md devices used by PVs.
That step needs to be restored, and is now included in
64-lvm.rules.
