early: remove superfluous close of stdio file descriptors

'man dup2' says:

  dup2() makes newfd be the copy of oldfd, closing newfd first if
  necessary, but note the following:

  *  If oldfd is not a valid file descriptor, then the call fails,
     and newfd is not closed.

  *  If oldfd is a valid file descriptor, and newfd has the same
     value as oldfd, then dup2() does nothing, and returns newfd.
