We presently prevent processes from using setexecon() to set the security label of exec()'d processes when NO_NEW_PRIVS is enabled by returning an error; however, we silently ignore setexeccon() when exec()'ing from a nosuid mounted filesystem. This patch makes things a bit more consistent by returning an error in the setexeccon()/nosuid case.
