Rather than using the most recent version of clang available in the selected Fedora release, source it from the Rust build. That provides an indirect form of pinning and control over what ships in the SDK, which is useful if BPF programs and other binaries might be compiled with clang.

pyelftools is required to build newer versions of systemd-boot. Signed-off-by: Ben Cressey <[email protected]>
When building BPF programs using libbpf-rs, it's necessary to link the build script that's compiled with the host toolchain with libbpf, while also linking the target's binary to the target's libbpf. Include libbpf-devel for this purpose. Signed-off-by: Ben Cressey <[email protected]>

N/A
Description of changes:
Add libbpf-devel to support downstream builds that use libbpf-rs.
Vendor clang and LLVM from the Rust build, to tighten control over the tool chain used to compile BPF programs.
Include pyelftools to enable building systemd-boot on aarch64.
Testing done:
Built a Rust program that used libbpf-rs to load a BPF LSM hook.
Built systemd-boot for arm64 on arm64. There are other problems with building for x86_64, but this is a start to unblock experiments.
