java/openjdk23: Delete patch for fontmanager/freetypeScaler.c

The patch causes a load failure when trying to load graphical java
programs, because it created a hard dependency on libfontconfig.so from
libfontmanager.so. This should be handled by the JDK itself by
dynamically loading fontconfig if it's needed.
