bpf: Make btf_get_module_btf() and btf_relocate_id() non-static
Drop the static qualifier and add prototypes to <linux/btf.h> so the
tracing core can look up module BTF and translate ids stored by
resolve_btfids (which are local to a module's split BTF) into the
runtime ids used by the kernel.
Used by the upcoming events/<sys>/<event>/btf_ids tracefs interface.
