Amends commit 7cf39bd785e8ba817960d48b120983cafcc539f3, which changed to
use QDirListing but used FilesOnly. As documented, that does not include
symlinks to files.
I'm updating a few other uses of FilesOnly where they were ported from
QDir::Files and it would be reasonable to expect that symlink to files
would be included. That's why I've left QNetworkDiskCache alone.
Fixes: QTBUG-130109
Pick-to: 6.8
