libctf: adjust dumper for symtypetab changes

Now that we have a new format for the function info section, it's much
easier to dump it: we can use the same code we use for the object type
section, and that's got simpler too because we can use ctf_symbol_next.

Also dump the new stuff in the header: the new flags bits and the index
section lengths.
