tools/resolve_btfids: Install subcmd headers
commit af03299d8536d62b49c7f3cb929349eb2d66bcd5 upstream. Previously tools/lib/subcmd was added to the include path, switch to installing the headers and then including from that directory. This avoids dependencies on headers internal to tools/lib/subcmd. Add the missing subcmd directory to the affected #include.
