[PATCH 5/5] tests/acceptance: Test PMON on the Fuloong 2E machine

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

Test the PMON firmware. As the firmware is not redistributable,
it has to be downloaded manually first. Then it can be used by
providing its path via the PMON_BIN_PATH environment variable:

  $ PMON2E_BIN_PATH=~/images/fuloong2e/pmon_2e.bin \
    AVOCADO_ALLOW_UNTRUSTED_CODE=1 \
    avocado --show=app,console run tests/acceptance/machine_mips_fuloong2e.py
