ueventd: populate /dev/block/mapper link
Since DM_NAME= is not sent (delete bug) or interpreted with ueventd
message, instead probe /sys/devices/virtual/block/dm-X/dm/name when
instantiating. Cache the value for later delete.
By creating the /dev/block/mapper/<name> nodes, this will give
selabel_lookup_best_match an alias to hang its hat on so that the
associated /dev/block/dm-X nodes will be suitably labelled and
differentiated.
NB: For Android, the deletion of the nodes will only happen in the
context of fastbootd, update_engine and gsid; otherwise the links
and properties created can be considered set-once and persistent.
Test: manual inspect /dev/block/mapper/ links
