GH-46879: [CI][Packaging][Linux] Don't check example build with old CMake

[kou]

Rationale for this change

#46834 required CMake 3.25 or later for an example CMake project.

What changes are included in this PR?

Don't build the example CMake project with CMake < 3.25 in package verification. Amazon Linux 2023, CentOS 7 and Ubuntu 22.04 don't provide CMake 3.25 or later.

Are these changes tested?

Yes.

Are there any user-facing changes?

No.
