BootLinuxConsoleTest: Test the RX GDB simulator

Add two tests for the rx-gdbsim machine, based on the recommended
test setup from Yoshinori Sato:
https://lists.gnu.org/archive/html/qemu-devel/2019-05/msg03586.html

- U-Boot prompt
- Linux kernel with Sash shell

These are very quick tests:

  $ avocado run -t arch:rx tests/acceptance/machine_rx_gdbsim.py
  JOB ID     : 84a6ef01c0b87975ecbfcb31a920afd735753ace
  JOB LOG    : /home/phil/avocado/job-results/job-2019-05-24T05.02-84a6ef0/job.log
   (1/2) tests/acceptance/machine_rx_gdbsim.py:RxGdbSimMachine.test_uboot: PASS (0.11 s)
   (2/2) tests/acceptance/machine_rx_gdbsim.py:RxGdbSimMachine.test_linux_sash: PASS (0.45 s)
  RESULTS    : PASS 2 | ERROR 0 | FAIL 0 | SKIP 0 | WARN 0 | INTERRUPT 0 | CANCEL 0

Tests can also be run with:

  $ avocado --show=console run -t arch:rx tests/acceptance/machine_rx_gdbsim.py
