Rename allow-query pytest glue file

To conform with the expected naming convention, the pytest glue file for
the `allow-query` test should use underscore as the word separator in
the python file name: allow-query/tests_sh_allow_query.py

(cherry picked from commit c026a00696)

bin/tests/system/allow-query/tests_sh_allow_query.py
