Revert "Move fuse-overlayfs to suggests" for Fedora 40 and older

Fedora completely ignores Suggests by default [1].  So, listing anything
as Suggests is as good as not mentioning it at all, unless it's intended
for tools and users who specifically respect it.

Downgrading the dependency on fuse-overlayfs to Suggests can make it go
missing from the user's system, and break old Toolbx containers [2].

This is a problem because when Fedora 40 was released, it included
containers-common-0.58.0-2.fc40 [3,4], which still had:
  Recommends: fuse-overlayfs
  Requires: (fuse-overlayfs if fedora-release-identity-server)

The change to Suggests in Fedora commit 447945e59a01cb67 ("Move
fuse-overlayfs to suggests") was made after that.

Such breaking changes are not meant for stable Fedora releases to avoid
surprising users, and are best done in the next upcoming version [5].
This is particularly true for atomic Fedora variants like Silverblue,
where the fuse-overlayfs RPM fell off the operating system image and had
to be reinstated [6].  It could also happen to those using other Fedora
variants, if, for example, they were trying to use a Kickstart for
installation.

This reverts Fedora commit 447945e59a01cb6715ed2a21877d45bf0b91ef67 for
Fedora 40 and older releases.
