[Patch testsuite obvious] Use setjmp, not sigsetjmp in gcc.dg/pr78582.c

[James Greenhalgh]

As subject.

Newlib doesn't have sigsetjmp, so the test fails for our newlib-based
testruns. Confirmed that this adjusted test would still have ICE'd
without r242958.

Committed as obvious as revision 243116.

Thanks,
James
