    libbpf: Add missed btf_ext__raw_data() API
    
    [ Upstream commit b9551da8cf3ade01a50316df8a618fd945723ee0 ]
    
    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.
