fix #4355: d/control: depend on binutils to ensure objdump is available

Reported both in BZ and the forum, with the latter posting the
output of `pct start <vmid> --debug` it quickly became obvious that
we miss the binutils dependency here, maybe we can drop that in the
future again by simply parsing the ELF header in rust and use perlmod
but as stop gap for now just ensure that we actually got the tools
available we want to use..
