Add EXCLUDED_CRATES and better default names

* protobuf_bin_gen_rust_do_not_use is in EXCLUDED_CRATES
* build_default_name returns a short and readable name
  for a rust_defaults module, from the following choices:
    (1) root_pkg + '_defaults',
    (2) root_pkg + '_defaults_' + crate_name
    (3) root_pkg + '_defaults_' + main_src_basename_path
    (4) root_pkg + '_defaults_' + a_positive_sequence_number

Test: regen external/rust/crates/*/Android.bp
