xserver_xorg-server: add upstream patches to fix build issue

Fixes the following build issue with gcc 4.6:

  LINK  Xfbdev
.../host/opt/ext-toolchain/bin/../lib/gcc/arm-none-linux-gnueabi/4.6.1/../../../../arm-none-linux-gnueabi/bin/ld: ../../../os/.libs/libos.a(backtrace.o): undefined reference to symbol 'dladdr@@GLIBC_2.4'
.../host/opt/ext-toolchain/bin/../lib/gcc/arm-none-linux-gnueabi/4.6.1/../../../../arm-none-linux-gnueabi/bin/ld: note: 'dladdr@@GLIBC_2.4' is defined in DSO .../host/usr/arm-unknown-linux-gnueabi/sysroot/lib/libdl.so.2 so try adding it to the linker command line
.../host/usr/arm-unknown-linux-gnueabi/sysroot/lib/libdl.so.2: could not read symbols: Invalid operation

+Subject: Add missing DLOPEN_LIBS to kdrive compilation flags
+
+Xfbdev failed to build due to dladdr being used by xorg_backtrace.
+Explicitly add DLOPEN_LIBS to KDRIVE_LIBS as there does not
+seem to be a better place for it.

+Subject: Supply all code using dl*() with DLOPEN_LIBS
+
+Previously DLOPEN_LIBS was managed in top-level configure.ac.
+Instead bundle it with the code using dl*() functions to
+avoid breakages in uncommon configurations.
