xserver-xorg: remove redundant patch

Upstream doesn't assume a monotonic clock isn't available anymore, so we can
remove this patch.

-Subject: [PATCH] Discover monotonic clock using compile-time check
-
-monotonic clock check does not work when cross-compiling.
-
-Upstream-Status: Denied [Does not work on OpenBSD]

-Original patch follows:
-
-When xorg-xserver is being cross-compiled, there is currently no way
-for us to detect whether the monotonic clock is available on the
-target system, because we aren't able to run a test program on the host
-system. Currently, in this situation, we default to not use the
-monotonic clock. One problem with this situation is that the user will
-be treated as idle when the date is updated.
-
-To fix this situation, we now use a compile-time check to detect whether the
-monotonic clock is available. This check can run just fine when we are
-cross-compiling.
