support for per-partition fs_type
Include the recovery.fstab file in the recovery image. Remove the
global fs_type and partition_type values from the target-files
key/value dict, and parse the recovery.fstab file instead to find
types for each partition.
(Cherrypicked from gingerbread w/some edits to resolve conflicts.)
