X11: Fix glfwWaitEvents* ignoring joystick events
The data available on the X11 connection may be a reply or an internal event for an X11 extension. Previously the check for whether an event was available for us was done outside waitForEvent. This prevented data available on other file descriptors from breaking the outer wait loop. This commit moves the check for whether an event is available into the wait functions, where there is enough knowledge to limit the check to the X11 connection. Related to #932
