testsuite: Use sigsetjmp in gcc.misc-tests/gcov-31.c

The gcc.misc-tests/gcov-31.c test FAILs on Solaris and Darwin:

FAIL: gcc.misc-tests/gcov-31.c (test for excess errors)

Excess errors:
/vol/gcc/src/hg/master/local/gcc/testsuite/gcc.misc-tests/gcov-31.c:23:5:
error: implicit declaration of function '__sigsetjmp'; did you mean
'sigsetjmp'? [-Wimplicit-function-declaration]

__sigsetjmp is a Linux/glibc implementation detail.  Other tests just
use sigsetjmp directly, so this patch follows suit.

Tested on i386-pc-solaris2.11, sparc-sun-solaris2.11,
x86_64-pc-linux-gnu, and x86_64-apple-darwin24.4.0.

	gcc/testsuite:
	* gcc.misc-tests/gcov-31.c (run_pending_traps): Use sigsetjmp
	instead of __sigsetjmp.
