xterm-console-1.0-bp154.1.21

- Update to version 1.0:
  * Change package to use upstream on
    https://github.com/os-autoinst/xterm_console
  * Change to noarch as there are only scripts
  * Delete old pre-SLE11 cruft
  * Cleanup spec-file (delete unused symbol; simplify)

- Use supplemments to os-autoinst
  When using svirt backend (s390x, XEN), xterm-console is needed.
  It is expected the use of this backend only on special cases,
  so this package is not added as required. But it may help to
  mark it as supplement os os-autoinst.

- remove nonexistant +itc option

- initial version
