Add support for displaying opcodes or/and file references (filepath, line and column numbers) when dumping the control flow graphs of loaded BPF programs with bpftool. The filepaths in the records are absolute. To avoid blocks on the graph to get too wide, we truncate them when they get too long (but we always keep the entire file name). In the unlikely case where the resulting file name is ambiguous, it remains possible to get the full path with a regular dump (no CFG).
