[PATCH] git-compat-util.h: remove superfluous test for __sun__

From: Brandon Casey <redacted>

This 'ifndef' macro is entered only when __sun__ is not defined.  This test
will never fail since it is located inside of the 'else' branch of an 'if'
macro which tests whether __sun__ is defined.  It has had no effect since
the merge at 436f66b7.
