xlib_libX11: re-add a patch to fix the keysymdef issue

When xlib_libX11 was bumped to 1.3.2 in commit
1d956c9190, the keysymdef patch was
dropped. However, this patch is still needed in order to be able to
tell ./configure where the keysymdef header file is installed.

The patch has been updated for 1.3.2.

+[patch]: configure: add --with-keysymdef argument for cross compilation
+
+Based on a similar patch from Openembedded.
+
+The libX11 configure script hardcodes the location to keysymdef.h as
+<prefix>/include/X11/keysymdef.h, which is fine for native compilation,
+but breaks with cross compilation as that directory is a location on
+the target, not the build host.
+
+Fix it by providing an explicit --with-keysymdef=<full-path-to-file>.
