file-type: add support for doors and other less-common file types

Problem with S_ISDOOR reported by Rich Burridge.
* lib/file-type.c (file_type): Do S_ISLNK early too.  Do S_TYPEIS*
macros before the rest.  Add S_ISCTG, S_ISDOOR, S_ISMPB, S_ISMPC,
S_ISMPX, S_ISNAM, S_ISNWK, S_ISOFD, S_ISOFL, S_ISPORT, S_ISWHT.
