GH-47506: [CI][Packaging] Fix Amazon Linux 2023 packages verification (#47507)

### Rationale for this change

`gcc-c++` installs `kernel6.12-headers` automatically but it conflicts with `kernel-headers` that is required by `grpc-devel`.

### What changes are included in this PR?

Use `--allowerasing` to use `kernel-headers` when we install `grpc-devel`.

`gcc-c++` works with either `kernel6.12-headers` or `kernel-headers`. So this is not a problem.

### Are these changes tested?

Yes.

### Are there any user-facing changes?

No.
