bcache-tools: bcache-export-cached doesn't match backing device w/ offset, features

updated the awk snippet used in 'bcache-export-cached' so it matches the three
current superblock versions of a "backing" device (BCACHE_SB_VERSION_BDEV,
BCACHE_SB_VERSION_BDEV_WITH_OFFSET, BCACHE_SB_VERSION_BDEV_WITH_FEATURES)
