    [binutils] Handle DW_UT_skeleton/split_compile in process_debug_info

    With this exec:
    ...
    $ gcc -gsplit-dwarf hello.c -gdwarf-5
    ...
    we run into:
    ...
    $ readelf -w a.out > READELF
    readelf: Warning: CU at offset c7 contains corrupt or unsupported unit
type: 4.
    readelf: Warning: CU at offset c7 contains corrupt or unsupported unit
type: 4.
    ...

    Fix this by handling DW_UT_skeleton and DW_UT_split_compile in
    process_debug_info.

    Note that this just adds the parsing of DWO_id, but not yet any printing of
    it.

    Tested on x86_64-linux.
