u-boot-xlnx.inc: Explicitly set builddir path

Previous Yocto releases, builddir path was set in u-boot.inc within poky layer.
Since u-boot-xlnx.inc inherits u-boot.inc, makefile configures and compiles
u-boot-xlnx in a build directory ( set by B) that is not the source directory.
In Dunfell, build directory path is moved from u-boot.inc to u-boot-common.inc
which is not inherited in u-boot-xlnx recipes. As a result, during the build,
makefile configures and compiles u-boot-xlnx from source directory resulting in
the following error:
tmp/work/zcu102_zynqmp-xilinx-linux/u-boot-xlnx/v2020.01-xilinx-v2020.1+gitAUTOINC+86c84c0d0f-r0/git
is not clean, please run 'make mrproper'

To fix the error, set builddir path (B) explicitly within u-boot-xlnx.inc
