x64: Use X defines in ia32-base.inc file

Use the XSERVER defines in conf/machine/include/ia32-base.inc to specify X
recipes to include. This is the standard approch used by the other Intel
machine.conf files. Also added a couple more X drivers to eliminate the errors
at X start (i965 and modesetting driver).
