Removing gtk2 support

[Glavo]

Our JavaFX application has some strange problems when using GTK3,
one of the problems is that some ScrollPanes cannot scroll up with the
mouse wheel.

These problems only occur when GTK3 is used on Linux. To avoid this
problem, we have to set jdk.gtk.version to 2.

I haven't found any information about this problem. Does anyone know what
may be the cause?
