Security: Don't fail the Argon2-related tests when it's not available on the test infrastructure.

These tests are not critical to the bcrypt functionality, they exist to reaffirm that the  underlying use of `password_hash()` and `password_verify()` supports this algorithm. The Argon2 tests therefore shouldn't unnecessarily fail on hosts that don't support it.

Props desrosj, johnbillion.

Fixes #21022
