webkit: fix compilation without X11

Fixes:
 http://autobuild.buildroot.net/results/86534588d192fe1515ce520c109e884864871d94/
and others.

Webkit includes X11 headers even when configuerd for DirecfFB, because
the test within GNUmakefile.in does not work properly. Autoreconfigure
fails because of incompatibility with buildroot's autotools version.

For now a patch for GNUmakefile.in fixes this problem.

Since webkit release is quite old it doesn't seem to be worth doing more,
on the long run we should bump the version.

+Subject: [PATCH] Fix test for presence of X11
+
+The test in GNUmakefile.in checking for presence of X11 and
+enabling the XP_UNIX define succeeds even when X11 is not
+present and Webkit is built for DirectFB.
+
+Because of this X11-headers are included and the build fails.
