Basic virtio-fs support has made it upstream in the Linux kernel, as
well as in QEMU and Cloud Hypervisor. Let's go ahead and add it to the
standard configuration.
Since the device driver / DAX handling is still in progress for
upstream, we will want to still build a seperate experimental kernel for
those who are comfortable trading off bleeding edge stability/kernel
updates for improved FIO numbers.

Since we always build musl kata-agent, there is no need to build
it inside a musl container. We can just build on the host and then
copy the binary to the target rootfs.
There are still a lot to clean up and it should be made so for ALL
target distros instead of just alpine. But this is at least working
for alpine first.

Now, cloud-hypervisor is capable to work on arm64. it's time to
enable it in kata for arm64.
as cloud-hypervisor can only use virtio-fs, a new patch should be
applied to kernel for virtiofs and some config should be removed
temporarily.
