tools/misc: Drop xencons

This script is not python3 compatible, but has its shebang altered to say
python3 by INSTALL_PYTHON_PROG.

The most recent reference I can find to this script (which isn't incidental
adjustments in the makefile) is from the Xen book, fileish 561e30b804 which
says

  %% <snip>  Alternatively, if the
  %% Xen machine is connected to a serial-port server then we supply a
  %% dumb TCP terminal client, {\tt xencons}.

So this a not-invented-here version of telnet.  Delete it.
