Fixed by having krb5_fcc_interpret call krb5_set_error_message to incorporate

the lower-level error message into the message displayed by kinit, which has
already been changed to use krb5_get_error_message.  For example, "kinit(v5):
Credentials cache I/O operation failed (No space left on device) when
initializing cache".
