boot-state-efi fix for conf file renaming after successful boot

After successful booting of amd64, boot-state-efi is again renaming the .conf file. aum_boot_state_efi_conf_file_save() is being called after marking the boot successful.

Fix: state->update_available is being updated now and is passed with get_update_available returning the state.
