Call glFinish right after swap_buffers on X11
On X11 `swap_buffers` does not block for vsync. However the next OpenGl command
will block to synchronize (this is `glClear` in Alacritty), which causes a
permanent one frame delay.
Calling `glFinish` after swapping buffers forces Alacritty to finish the buffer
swap before returning control to the event loop.
Fixes #3061.
