update_engine: Replace libprotobuf with protobuf-lite.

This adds the option to the .proto file to generate the code as
libprotobuf-lite compatible since update_engine nor delta_generator
rely on reflection support from the generated protobuf class.

gyp file was updated to use the libprotobuf-lite flags as
specified by pkg-config.

BUG=chromium:383182,chromium:403588
TEST=cros deployed on link and attempted an update from there.
TEST=ldd update_engine shows libprotobuf-lite.
TEST=Tested delta_generator compatibility with old signed images.
