[PATCH] git-compat-util.h: remove redundant code

Since commit 3a0a3a89 ("git-compat-util.h: don't define _XOPEN_SOURCE
on cygwin", 23-11-2014) removed the definition of _XOPEN_SOURCE on
cygwin, the code within a pre-processor conditional further down the
file became redundant. Remove the redundant code.

This effectively reverts commit 41b20017 ("Fix an "implicit function
definition" warning", 03-03-2007).

Hi Junio,

I have a very vague recollection (back in March 2007) of trying to fix
the problem from commit 41b20017 using the solution in commit 3a0a3a89.
However, I can't remember the result! :(

I guess, by implication, there is a chance that it failed because (at
that time) something required _XOPEN_SOURCE to be set on cygwin. It is
clearly not the case for the current version of cygwin (v1.7.34, x86_64).
(I also tested on my old 32-bit laptop with an older cygwin - it's been
about a year since I updated that version of cygwin.)

[Hmm, would it be easier to change the conditional(s) to set _XOPEN_SOURCE
only for systems that require it (rather than avoid setting it for those
that don't)! I suspect only sun, AIX 5.3L and OpenBSD need it set. dunno.]

ATB,
Ramsay Jones
