RFR: JDK-8190725: Freetype license file provided with configure not included in images

Fri Nov 3 20:34:25 UTC 2017

The inclusion of the freetype license file has stopped working. For the 
-ri windows profile, we set --with-freetype-license, but the makefile 
logic for creating the java.desktop jmod is broken and doesn't pick it 
up. This patch fixes the FindModuleLegalDirs macro so that 
support/modules_legal/$MODULE gets included as well.
