testsuite: Adjust powerpc pr83677.c for BE [PR108815]

The test case gcc.target/powerpc/pr83677.c was written for
LE environment, this patch is to make it work on BE as well.

	PR testsuite/108815

gcc/testsuite/ChangeLog:

	* gcc.target/powerpc/pr83677.c (v_expand_u8, v_expand_u16,
	v_load_deinterleave_f32, v_store_interleave_f32): Adjust some code by
	considering BE.
