yamt 44f7683783 fix descriptor leaks. PR/47805 
this fix was taken from FreeBSD SVN rev 199953 (Jilles Tjoelker)
    ------------------------------------------------------------------------
    r199953 | jilles | 2009-11-30 07:33:59 +0900 (Mon, 30 Nov 2009) | 16 lines

    Fix some cases where file descriptors from redirections leak to programs.

    - Redirecting fds that were not open before kept two copies of the
      redirected file.
	sh -c '{ :; } 7>/dev/null; fstat -p $$; true'
	(both fd 7 and 10 remained open)
    - File descriptors used to restore things after redirection were not
      set close-on-exec, instead they were explicitly closed before executing
      a program normally and before executing a shell procedure. The latter
      must remain but the former is replaced by close-on-exec.
	sh -c 'exec 7</; { exec fstat -p $$; } 7>/dev/null; true'
	(fd 10 remained open)

    The examples above are simpler than the testsuite because I do not want to
    use fstat or procstat in the testsuite.
