[OpenJDK 2D-Dev] 8251367: [windows] harfbuzz.dll not found causes failure to load sun.font.SunFontManager

[Philip Race]

bug: https://bugs.openjdk.java.net/browse/JDK-8251367
webrev: http://cr.openjdk.java.net/~prr/8251367/

When using something other than the java launcher (ie the jpackage launcher)
harfbuzz.dll is not found by windows dll loading.
So we need to load it explicitly else the Java class that loads 
fontmanager,dll
will fail to initialize.

At the same time, I'd like to fix a very minor inconsequential pair of 
typoes
that exclude from the build files by the wrong directory pathname.
