package/zynq-boot-bin: drop legacy package

Since commit 6dd5a33c485c (zynq_zed: bump U-Boot to xilinx-v2016.2), we
have no in-tree users of zynq-boot-bin.py, as U-Boot has since v2016.01
been able to natively generate Xilinx images.

zynq-boot-bin.py is python2-only and there is zero chance that upstream
will move it to python3. We could carry a python3-compatible copy, but
that tool is now virtually unused.

6 years have passed now; let it rest in peace at last.
