libbpf: Add missed btf_ext__raw_data() API

Browse Source 
Another API that was declared in libbpf.map but actual implementation
was missing. btf_ext__get_raw_data() was intended as a discouraged alias
to consistently-named btf_ext__raw_data(), so make this an actuality.

Fixes: 20eccf29e297 ("libbpf: hide and discourage inconsistently named getters")
