testsuite: Fix up fixed-point/bitint-1.c test

This test was written without _BitInt support on any target with
fixed-point support as well, so was actually never tested.

Now that it can be tested on loongarch64-linux, there is a missing
expected error, so this patch adds it.

	* gcc.dg/fixed-point/bitint-1.c: Expect also error about _Sat used
	without _Fract/_Accum.
