lib:r3p0:hf:x11: disable egl destructor

Hexedit bx lr (a ret for arm) into the body of __LINUXeglDestructor.
This stops our EGL from attempting to clean up any remaining DRI2
drawables, which, when run after XCloseDisplay() or the likes, gets us
lots of undefined behaviour, like deadlocks and such.
