hfsplus: emit proper file type from readdir
hfsplus_readdir() incorrectly returned DT_REG for symbolic links and
special files. Return DT_REG, DT_LNK, DT_FIFO, DT_CHR, DT_BLK, DT_SOCK,
or DT_UNKNOWN according to mode field in catalog record. Programs
relying on information from readdir will now work correctly with HFS+.
