ff6122f32b doc: clarify protobuf build requirements (fanquake)

Pull request description:

  As mentioned by dongcarl in https://github.com/bitcoin/bitcoin/pull/15584#issuecomment-521780972, make building `protobuf` optional in depends. With this change it will only be built if you pass `PROTOBUF=1`.

ACKs for top commit:
  laanwj:
    code review ACK 107e030723
  Sjors:
    tACK 107e030 on macOS 10.14. When I build depends with `PROTOBUF=1` then `./configure` has `bip70` enabled.

* Berkeley DB is not needed with `--disable-wallet`.
* protobuf is not needed with `--disable-bip70`.
* protobuf is only needed with `--enable-bip70`.
* Qt is not needed with `--without-gui`.
* If the qrencode dependency is absent, QR support won't be added. To force an error when that happens, pass `--with-qrencode`.
