tests/pixbuf-reftest: Work around broken symlinks on Windows

When cloning the repo with git on Windows the symlinks end up being
normal files which contain the target path as text.

Make this kinda work by detecting if the files contain ascii only
and then treating the content as a filename in the parent directory.
