Remove unnecessary umask change in text_save_begin_inplace

POSIX says that

  The mkstemp() function shall use the resulting pathname to create the
  file, and obtain a file descriptor for it, as if by a call to:

    open(pathname, O_RDWR|O_CREAT|O_EXCL, S_IRUSR|S_IWUSR)

So this umask change didn't do anything in practice, unless the original
umask was more restrictive than 0177.
