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.
