[Buildroot] [PATCH v6 0/6] kvm-unit-tests: update deps and fine tune qemu

["Alex Bennée" <alex.bennee@linaro.org>]

The kvm-unit-tests recipe is a little out of date with the
dependencies it needs. With that and some tweaking of the of processor
dependencies we can now build kvm-unit-tests for arm64.

As kvm-unit-tests need the libc utils and I use external tooling I
added support for that.

On the way I've added some new config options for QEMU so you can just
select your native, kvm-only QEMU build.

For Arm we can also run with kvmtool so I've added an option to enable
that.

Finally I've added a simple test case for the kvm-unit-tests package.

The following patches are unreviewed:

  support/testing: add test for kvm-unit-tests
  toolchain/external: allow installing of libc utils

Otherwise I think everything is good to go.

For v6
  - some patches merged

For v5
  - more r-b tags
  - addressed comments (see commits)

For v4
  - re-base
  - update kvm-unit-tests to v2025-07-31

For v3
  - add r-b tags
  - update kvm-unit-tests to current master
  - update kvmtool
  - enable kvmtool as alternative to QEMU

For v2
  - addressed review comments
  - added external libc util support
  - added test case
  - ran and addressed linter warnings

Alex.
