[PATCH v2 xserver] xwayland: Enable DRI3 for glamor

[Olivier Fourdan]

glamor_fds_from_pixmap() will bail out early if DRI3 is not enabled,
unfortunately Xwayland's glamor code would not set it as enabled which
would lead to blank pixmaps when using texture from pixmap.

Make sure to mark DRI3 as enabled from glamor_egl_screen_init() in
Xwayland.
