d-ino: avoid false negative on symlink
If the first entry listed in a directory is a symlink, we
had a spurious mismatch between d_ino (which should match the
symlink) and stat() results (which chases the symlink).
Reported by Stephane Chazelas <stephane.chazelas@gmail.com>.
* m4/d-ino.m4 (gl_CHECK_TYPE_STRUCT_DIRENT_D_INO): Use lstat.
