[zbin] Allow decompressor to generate debug output via BIOS console

The 0xe9 debug port exists only on virtual machines.  Provide an
option to print debug output on the BIOS console, to allow for
debugging on real hardware.

Note that this option can be used only if the decompressor is called
in flat real mode; the easiest way to achieve this is to build with
DEBUG=libprefix.
