[issue45502] Fix test_shelve and make it discoverable

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

test_shelve was intended to run some tests for all underlying dbm implementation, but since b17acad68ea21c60dbc2088644f2934032304628 (at May 2008) it runs them with the same implementation.

The proposed PR fixes this regression and also makes test_shelve discoverable, so it can be run with the unittest module.
