Knowing that the upstream project provides a "ready to use" version of
the kernel, it's good to include an easy way to users to monitor
performance, and that's what we're doing by enabling the TASKSTATS (and
related) kernel configs.
This has been present as part of older kernels, but I couldn't
reasonably find the reason why it's been dropped.

Set CONFIG_BLK_DEV_WRITE_MOUNTED=y to restore previous kernel behaviour.
Kernel v6.8+ will by default block buffer writes to block devices mounted by filesystems.
This unfortunately is what we need to use mounted loop devices needed by some teams
to build OSIs and as an overlay backing store.

KinD checks for the presence of this (and other) kernel configuration
via scripts like
https://blog.hypriot.com/post/verify-kernel-container-compatibility/ or
attempts to directly use /proc/sys/kernel/keys/ without checking to see
if it exists, causing an exit when it does not see it.
Docker/it's consumers apparently expect to be able to use the kernel
keyring and it's associated syscalls from/for containers.
There aren't any known downsides to enabling this except that it would
by definition enable additional syscalls defined in
https://man7.org/linux/man-pages/man7/keyrings.7.html which are
reachable from userspace. This minimally increases the attack surface of
the Kata Kernel, but this attack surface is minimal (especially since
the kernel is most likely being executed by some kind of hypervisor) and
highly restricted compared to the utility of enabling this feature to
get further containerization compatibility.

While enabling the attestation for IBM SE, it was observed that
a kernel config `CONFIG_S390_UV_UAPI` is missing.
This config is required to present an ultravisor in the guest VM.

`CONFIG_TN3270_TTY` and `CONFIG_S390_AP_IOMMU` are dropped for s390x
in 6.7.x which is used for a confidential kernel.
But they are still used for a vanilla kernel. So we need to add them
to the whitelist.

This is already done for the TDX kernel, and should have been done also

This action requires us to bump the kernel version as the resulting

We're using a Kernel based on v6.7, which should include all te
patches needed for SEV / SNP / TDX.
By doing this, later on, we'll be able to stop building the specific
kernel for each one of the targets we have for the TEEs.
Let's note that we've introduced the "confidential" target for the
kernel builder script, while the TEE specific builds are being kept as
they're -- at least for now.

There were recent changes for the tdx kernel in the version.yaml that are
not currently accounted for in the build-kernel.sh script.
Attempts to setup a tdx kernel to build local changes seemed to not download
the tdx kernel. Instead the mainline kernel is downloaded which has no
tdx-related changes.
The version.yaml has a new entry for tdx kernel. Use that instead for
setting up and downloading the tdx kernel.
