x11: add modesetting to the xpresent whitelist 

Since the modesetting driver now has TearFree support with integration into
xpresent, it's important that xpresent is used with the modesetting driver
to get the correct vsync timing when a frame is delayed by one vblank
interval due to a pending page-flip enqueued by a different entity. The
modesetting driver ensures that the xpresent extension reports the correct
presentation timing when TearFree is used; mpv just needs to listen to it.

Add the modesetting driver to the xpresent whitelist so mpv can get the
correct presentation completion timing when modesetting TearFree is used.

This is also helpful for when xpresent performs page flips directly in the
modesetting driver and a natural delay in the display pipeline causes a
page flip to be delayed by one vblank interval or more.
