xserver-xorg: Backport patch to remove using sys/io.h

latest glibc dropped support for sys/io.h on arm, which is fixed in
upstream xserver, as a bonus we can drop musl specific patch which was
doing something similar up until now.

+Subject: [PATCH] compiler.h: Do not include sys/io.h on ARM with glibc
+
+<sys/io.h> on ARM hasn't worked for a long, long time, so it was removed
+it from glibc upstream.
+
+Remove the include to avoid a compilation failure on ARM with glibc.
