[PATCH 2/7] tools/misc: Drop xencons

[Andrew Cooper <andrew.cooper3@citrix.com>]

This is a python script which has it's shebang modified by be python3, but
was never converted to be python3 compatible.

The most recent reference I can find to this script (which isn't incidental
adjustments in the makefile) is from the Xen book, fileish 561e30b80402 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.
