goldfish-opengl: fix build breakage

There has been some refactoring on master and it does not
consider the fact this project is shared by old branches.

This CL checks for PLATFORM_VERSION_CODENAME.PPR1 and make
adjustment to get it work on both master and older branches

Once the O is finalized as api 26 we can remove the CODENAME
hack
