vulkan: delete typo'd header
Two files exist in that directory:
- vulkan_xlib_randr.h
- vulkan_xlib_xrandr.h
Both were imported in
205c271562db8cb2effc ("vulkan: Update the XML and
headers to 1.1.70") with identical contents (ie. the
VK_EXT_acquire_xlib_display extension), but the former was never
included anywhere and can't be found upstream [1], while the latter is
included in vulkan.h and found upstream.
