RFR: JDK-8056215 AWT source dirs should only point to java2d, not below

Mon Nov 28 09:47:37 UTC 2016

This is from a code review following the jigsaw source file restructuring:

* The makefiles include too specific directories. Instead of including 
e.g. ./*/native/common/sun/java2d/opengl and 
./*/native/common/sun/java2d/x11, we should just include 
./*/native/common/sun/java2d. This level corresponds to a logical 
grouping of the source code, and not the directory structure in that 
grouping.
