Replace copysign (0,-1) with -0.0 in initializer

GCC 4.9 issues an error for copysign in initializer:

In file included from tst-printf-format-p-double.c:20:0:
tst-printf-format-skeleton-double.c:29:3: error: initializer element is not a constant expression [-Werror]
   { -HUGE_VAL, -DBL_MAX, -DBL_MIN, copysign (0, -1), -NAN, NAN, 0, DBL_MIN,
   ^

since it can't fold "copysign (0, -1)".  Replace copysign (0,-1) with -0.0.
