[PATCH 09/26] tests/acceptance: Add bFLT loader linux-user test

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

Add a very quick test that runs a busybox binary in bFLT format:

  $ avocado --show=app run tests/acceptance/load_bflt.py
  JOB ID     : db94d5960ce564c50904d666a7e259148c27e88f
  JOB LOG    : ~/avocado/job-results/job-2019-06-25T10.52-db94d59/job.log
   (1/1) tests/acceptance/load_bflt.py:LoadBFLT.test_stm32: PASS (0.15 s)
  RESULTS    : PASS 1 | ERROR 0 | FAIL 0 | SKIP 0 | WARN 0 | INTERRUPT 0 | CANCEL 0
  JOB TIME   : 0.54 s
