If using mkfs.btrfs with "-r" parameter and specified direct has
fifo/socket/char/block special file, then created btrfs can't pass fsck:

checking fs roots
	unresolved ref dir 241158 index 3 namelen 9 name S.dirmngr filetype 0 errors 80, filetype mismatch
ERROR: errors found in fs roots

Btrfs dir items/indexes records inode type, while "-r" only handles
directors, regular files and soft link, it makes such special files type
to be regular file and caused the problem.

Add missing types for add_directory_items(), so that result of
"mkfs.btrfs -r" can pass mkfs.
