tests/system/etc/login.defs: set ENCRYPT_METHOD SHA512

Commit 609bd9194174d ("Remove support for DES") commented out
ENCRYPT_METHOD, which caused tests to use the container's default
password hashing. Linux-PAM still defaults to DES when the encryption
method isn't set in the configuration, but since the shadow code no
longer supports DES, tests fail.

Explicitly setting ENCRYPT_METHOD to SHA512 ensures tests use a
supported modern hashing algorithm regardless of container defaults

Fixes: 609bd9194174 (2026-07-17; "*/: Remove support for DES")
