Issue 6295 - test_password_modify_non_utf8 should set default passwor…

…d storage scheme

Bug Description:
Test dirsrvtests/tests/suites/password/password_test.py::test_password_modify_non_utf8
assumes the default password storage scheme is PBKDF2-SHA512, but it's not true
on old versions.

Fix Description:
The test should set PBKDF2-SHA512 explicitly, since it tests a crash in pwdchan
plugin that provides this storage scheme.

Fixes: 389ds#6295
