uboot-tools: use local libfdt.h

The use of libfdt.h by u-boot is using the
<system-path>.  The libfdt part of uboot
is expriencing a lot of change and this patch
should be overcome by events post uboot-2017.11
release.

+Subject: [PATCH] Do not attempt to use the systemwide libfdt
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+U-Boot bundles a patched copy of libfdt, so it's wrong to attempt to
+include it <like/this>. This breaks the build for me when I have dtc
+fully installed in my host -- as happened earlier tonight with
+Buildroot, for example.
+
+There are several other occurrences throughout the code where '<libfdt'
+matches. I'm not modifying these because I have no clue why the
+<systemwide> include style is being used -- IMHO wrongly.
