Adds py_unittest_qnx_test removed by baselibs

[rmaddikery]

• The wrapper is still needed to support the exports from internal repo while still having
  the test targets in place.
• baselibs refs: https://github.com/eclipse-score/baselibs/blob/v0.2.10/third_party/itf/py_unittest_qnx_test.bzl
• Follow-up task: use score_qnx_unit_tests in py_unittest_qnx_test #267
