libbinder: use clang-format

For incremental adoption of clang-format. libbinder has an old way of
formatting things, a way which I haven't found specific documentation
for. This should incrementally fix it up as well as help us format new
things without needing to think/worry about it too much.

Note - due to internal merge conflicts, an extra line for
/binder/fuzzer is left here.
