[tests] OpenBSD crypt() support limited to bcrypt

OpenBSD crypt() does not support (insecure) crypt-des or crypt-md5

(The password used in the tests and lighttpd.htpasswd is crypt-des.
 Something else could be used so that the tests can execute,
 though that something might be different on different platforms.)
