gomp: testsuite: improve compatibility of bad-array-section-3.c [PR113428]

This test generates different warnings on ilp32 targets because the size
of an integer matches the size of a pointer.  Avoid this by using
signed char.

gcc/testsuite:

	PR testsuite/113428
	* gcc.dg/gomp/bad-array-section-c-3.c: Use signed char instead
	of int.
