find7: LVM partitioning support (phase 1)

This just adds the LVM prebuilt to recovery and normal ramdisks,
reconfiguration of storage is a separate patch

This binary is the same one in the aries ramdisk of both CM and Omni
which is built from source at https://github.com/steven676/android-lvm-mod

TODO:  Keep our own local copy of these sources to ensure GPL compliance
in the event that steven676's repo ever dies
