testsuite: Check int128 effective target for pr109932-{1,2}.c [PR110230]

This patch is to make newly added test cases pr109932-{1,2}.c
check int128 effective target to avoid unsupported type error
on 32-bit.  I did hit this failure during testing and fixed
it, but made a stupid mistake not updating the local formatted
patch which was actually out of date.

	PR testsuite/110230
	PR target/109932

gcc/testsuite/ChangeLog:

	* gcc.target/powerpc/pr109932-1.c: Adjust with int128 effective target.
	* gcc.target/powerpc/pr109932-2.c: Ditto.

(cherry picked from commit 16eb9d69)
