LU-11753 utils: print out DNE2 directory hash flags

There may be flags stored in the lmv_hash_type field, such as
"LMV_HASH_FLAG_MIGRATION" that is set while the directory is
being migrated.  Print out the flag from "lfs getdirstripe".

This is still missing support for "lfs find" to find directories
that have incomplete migration.
