Remove -Wall from default build options

All bazel crosstools automatically pass -Wall to compiles. The order of
operations is:

- bazel crosstool flags
- `--host_copt` flags and other variations like `--host_cxxopt`
- the `copts` defined on the rule

Because of this when protobuf produces warnings, there's no way to
disable them from the consumer side if they are re-enabled later by
another `-Wall` flag.
