Privacy: Use a CSPRNG in export filenames for more security.

`rand()` is deterministic and therefore offers much less protection in this context. `wp_generate_password()` is a convenient wrapper around `wp_rand()`, which uses `random_int()` to generate cryptographically-secure psuedorandom numbers.

See #43546.
