package/x11r7/xdriver_xf86-video-openchrome: switch dependency from mesa3d to libgl

DRI support for this driver is provided by the xserver_xorg-server
package when BR2_PACKAGE_HAS_LIBGL is enabled:
https://git.busybox.net/buildroot/tree/package/x11r7/xserver_xorg-server/xserver_xorg-server.mk#n91

Change the dependency to follow the logic of xserver_xorg-server.
