efi_loader: efi_auth_var_type for AuditMode, DeployedMode
Writing variables AuditMode and DeployedMode serves to switch between
Secure Boot modes. Provide a separate value for these in efi_auth_var_type.
With this patch the variables will not be read from from file even if they
are marked as non-volatile by mistake.
