Fix incorrect file type tests.
This bug caused sockets and character special devices to be accepted
as manual pages if they appeared inside manpaths, and
it caused incorrect file names to be entered into the database when
the manpath or one of its parent directories was a symbolic link.
This fixes the issues reported by <Andreas dot Kahari at abc dot se>
on ports@, but additional issues remain when symbolic links are
contained in a manpath that involves another symbolic link.
