anv: Link to libX11-xcb only when unneeded

The Makefile unconditionally linked libX11-xcb into libvulkan_intel.so.
But it's needed only if HAVE_PLATFORM_X11.

Fixes build of libvulkan_intel.so on Chromium OS, which has no X11
libraries.

Fixes: 71258e9462c ("anv/x11: Add support for Xlib platform")
