Peter Korsgaard 7e72901eef package/shadow: ensure that SHA support is enabled when requested
Ensure that the SHA_CRYPT option is enabled when the system configuration is
set to SHA256/512, as otherwise passwd complains when a password is changed:

passwd
...
Invalid ENCRYPT_METHOD value: 'SHA512'.
Defaulting to DES.
