Having the GPG check enabled for Google repos in `gce*` images will make
DNF try to import the relevant keys when upgrading, downgrading or
installing any packages from the repo. However due to Google still using
SHA-1 for GPG keys used to sign their RPMs, importing it will make any
transaction that includes such RPM to fail.
Disabling the GPG check will ensure that DNF won't attempt to import
Google GPG keys.

The repo is not needed any more, because the Google Cloud SDK is not
installed in the images by default. If anyone wants to install the SDK,
they can add the appropriate repo definition.
The Google SDK ships pre-compiled binaries. It is undesirable to install
it by default in `gce` and `gce-rhui` in its current shape. Also not
installing it does not anyhow affect the RHEL integration as the guest
OS in GCP.
Blueprint package set is now depsolved together with the OS package set
in a chain. The result is stored in the package specs sets under the OS
package set name.
In reality, the code was able to handle a `nil` package specs to be
passed to pipelines, however some parts were looking for the kernel
version in the blueprint package specs, which would be a bug.
Regenerated affected image test cases.
Google repositories use RSA/SHA1 for signing packages. However the SHA1
has been disabled by default on el9/c9s. Since osbuild-composer imports
GPG keys specified in the repository definition unconditionally, this
creates issues when installing rpms signed with the key by osbuild [1].
Remove GPG keys in all el9/c9s GCP repo definitions and disable GPG
signature verification until [2] is resolved.
