Fix get_dirent_type() for symlinks on MinGW/MSYS.
On Windows with MSVC, get_dirent_type() was recently made to return
DT_LNK for junction points by commit 9d3444dc, which fixed some
defective dirent.c code.
On Windows with Cygwin, get_dirent_type() already worked for symlinks,
as it does on POSIX systems, because Cygwin has its own fake symlinks
that behave like POSIX (on closer inspection, Cygwin's dirent has the
BSD d_type extension but it's probably always DT_UNKNOWN, so we fall
back to lstat(), which understands Cygwin symlinks with S_ISLNK()).
On Windows with MinGW/MSYS, we need extra code, because the MinGW
runtime has its own readdir() without d_type, and the lstat()-based
fallback has no knowledge of our convention for treating junctions as
symlinks.
Back-patch to 14, where get_dirent_type() landed.
