[Buildroot] Various runtime test failures on Gitlab CI

[Thomas Petazzoni <thomas.petazzoni@bootlin.com>]

Ricardo, Fran?ois, Yegor, Yann,

The last Gitlab CI pipeline on master
(https://gitlab.com/buildroot.org/buildroot/pipelines/75533041/failures)
shows a number of failures in our runtime tests.

Here are the failing tests:

  tests.package.test_python_treq.TestPythonPy3Treq
  tests.package.test_python_treq.TestPythonPy2Treq
  tests.package.test_python_crossbar.TestPythonPy3Crossbar
  tests.package.test_perl_io_socket_ssl.TestPerlIOSocketSSL
  tests.package.test_lua_http.TestLuajitHttp
  tests.package.test_lua_http.TestLuaHttp
  tests.init.test_systemd.TestInitSystemSystemdRwFull

And now, the details of the build failures:

 - For tests.package.test_python_treq.TestPythonPy3Treq and
   tests.package.test_python_treq.TestPythonPy2Treq, we're getting:

Traceback (most recent call last):

    self.assertIn("Connection refused", output[0])
AssertionError: 'Connection refused' not found in ":0: UserWarning: You do not have a working installation of the service_identity module: 'cannot import name 'verify_ip_address' from 'service_identity.pyopenssl' (/usr/lib/python3.7/site-packages/service_identity/pyopenssl.pyc)'.  Please install it from <https://pypi.python.org/pypi/service_identity> and make sure all of its dependencies are satisfied.  Without the service_identity module, Twisted can perform only rudimentary TLS client hostname verification.  Many valid certificate/hostname mappings may be rejected."

 - For tests.package.test_python_crossbar.TestPythonPy3Crossbar, we're
   getting

    self.assertEqual(exit_code, 0)

 - For tests.package.test_perl_io_socket_ssl.TestPerlIOSocketSSL,
   tests.package.test_lua_http.TestLuajitHttp and
   tests.package.test_lua_http.TestLuaHttp, we're getting:

 - For tests.init.test_systemd.TestInitSystemSystemdRwFull, we're
   getting:

    raise SystemError("System does not boot")
SystemError: System does not boot

Could you have a look and fix those issues ?

Thanks!
