Patch from Envoy: exclude emsdk targets for Bazel/gcc. Fixes #149.

Sigh, it looks that clang-format-9 is no longer available in Ubuntu packages. Could you update it to fix the CI?

Also, could you add a daily CI run on schedule to catch those regressions when they happen (see: https://github.com/proxy-wasm/proxy-wasm-cpp-host/blob/94497deb683e37c0fc54e252b600de1dd4d47406/.github/workflows/test.yml#L31-L32)?

Updated CI to use recent clang-format and run daily. PTAL.

addlicense wants me to add this to every BUILD file. Is that desired?

Probably due to https://github.com/google/addlicense/pull/127

Removed BUILD files from addlicense check for now.
