Description: Revert upstream default to GTK2
 OpenJDK 11 uses GTK3 by default for the GTK Look and Feel but it still
 has too many pending issues and artifacts and is not on par with GTK2
 support. This patch is the reverse of the upstream commit which ensures
 that GTK2 is tried before GTK3.

 When GTK3 becomes better supported we should drop this and update the
 dlopen_jre_depends variable in debian/rules accordingly.
