redhat/kernel.spec.template: Build rtla with BPF sample collection
Sample collection using BPF was introduced in 6.15 as a faster default
mechanism. The previous implementation using a tracefs pipe is now a
fallback.
This allows rtla to work properly when measuring on a large number of
CPUs, as well as reduces CPU usage on all systems.
Add build dependency on libbpf-devel, bpftool, and clang, and runtime
dependency on libbpf for rtla in order to enable rtla BPF sample
collection.
