Add support for LittleFS to blkid. Not included if FEATURE_BLKID_TYPE

LittleFS is a small fail-safe filesystem designed for embedded
systems. It has strong copy-on-write guarantees and storage on disk
is always kept in a valid state. It also provides a form of dynamic
wear levelling for systems that can not fit a full flash translation
layer. (https://github.com/geky/littlefs)
ARM has introduced it in its Mbed OS 5.7, so it starts to gain focus.
