    touch: Respect caller's umask
    
    Currently, if the caller has a umask of 002 or 000, the file gets created 
as 644
    anyway.
    
    Also, add O_WRONLY to the open call, since POSIX says that "Applications 
shall
    specify exactly one of the first five values (file access modes) below in 
the
    value of oflag".
