clang-format: PointerAlignment LEFT

This is the format used in libbinder, but it appears not to be
configured here. However - this is really strange - because
I know it must have been? Maybe the Google format changed?
However, I find it really shocking that we might have always
typed this correctly in libbinder. Certainly something
else broke the format here!?
