Update protoc support for libplatformprotos

Browse Source 
Allow properties to be overriden by arch variants.
Add include_dirs and local_include_dirs properties.
Pass -I . to fix:
   frameworks/base/proto/src/metrics_constants.proto: File does not
   reside within any path specified using --proto_path (or -I).  You
   must specify a --proto_path which encompasses this file.  Note that
   the proto_path must be an exact prefix of the .proto file names --
   protoc is too dumb to figure out when two paths (e.g. absolute and
   relative) are equivalent (it's harder than you think).

Test: m -j libplatformprotos
