This bump also includes another release 'ch-release-v6.12.8-20250422'
that changed the naming convention of the released kernel binaries
[1]. As a result, few changes are made to our integration tests and test
scripts.

scripts: Temporarily build kernel as part of CI

Updating the kernel to v6.12 has shown up a flaw in the workflow for our
binary kernel releases. The CI job that builds the binary kernel in the
cloud-hypervisor/linux repository fetches the config from the main
branch of the cloud-hypervisor/cloud-hypervisor repository. However the
CI job to update the kernel version to use is in the cloud-hypervisor
repository.

As a workaround - update the kernel config and version in the
cloud-hypervisor repository to point to v6.12 and use the ability to
build the kernel during the CI run. Once merged to main a new release
can be made in the linux respository which will build a binary asset
using the new config. After that release the CI jobs on the
cloud-hypervisor repository can changed back to using the binary kernel
assets.

ci: Constrain FW_URL to x86_64 one

With 0.5.0 release of `rust-hypervisor-firmware`, `aarch64` binary were
added to assets, which causes the `FW_URL` to have multiple download url
separated by a white space, thus our integration tests would fail.

Constrain `FW_URL` to `hypervisor-fw` to resolve this.
