The current installation method for AWS linux headers and tools is based on downloading them from `ports.ubuntu.com` or `archive.ubuntu.com`, and then installing them with `dpkg -i`. Unfortunately, the current implementation doesn't work, because AWS headers are split into two packages: for example, headers for kernel `6.5.0-1024-aws` are split into `linux-headers-6.5.0-1024-aws` and `linux-aws-6.5-headers-6.5.0-1024`; both must be installed in order for anything using headers to work. Fix this headers and tools using directly the package manager. Signed-off-by: Leonardo Di Giovanna <leonardodigiovanna1@gmail.com>

Pin `modernprobe-builder` base image to`fedora:39`. Fedora 39 is deprecated, but this ensures working BPF object files build to run our distro/kernel tests. In the future, we can upgrade this after we investigate more the issues related to modern `clang` versions. Signed-off-by: Leonardo Di Giovanna <leonardodigiovanna1@gmail.com>

Disable BPF tests for both `oraclelinux-5.4-x86_64` and `oraclelinux-5.15-aarch64`. The VMs rootfs are based on `oraclelinux:8` and `oraclelinux:9`, which unfortunately provide a too much recent clang version (clang 20). This version doesn't work well wil the kernel expectation, and results in failing legacy BPF tests. BPF tests are disabled through a new `skip_legacy_bpf_tests` property in machine specification (see `ansible-playbooks/group_vars/all/vars.yml`). The new mechanism works by disabling legacy BPF support if the property is defined and set to true. Signed-off-by: Leonardo Di Giovanna <leonardodigiovanna1@gmail.com>

I conducted some tests and this machine seems to correctly work. Reintroduce it. Signed-off-by: Leonardo Di Giovanna <leonardodigiovanna1@gmail.com>
This is a temporary solution to make ubuntu-6.5 tests available on aarch64. Unfortunately, the newer images don't work, due to the fact that internal VM networking is not properly configured: specifically, the VM is able to ask for networking configuration to the external dnsmasq service, but the configuration is, for some reason, re-set after OS booting. While we investigate this issue, use the working old image. Furtunately, the old image has a recent enough cmake version (3.27.4). Signed-off-by: Leonardo Di Giovanna <leonardodigiovanna1@gmail.com>
