[PATCH] rs6000/test: Adjust fold-vec-extract-double.p9.c for BE [PR108810]

[Kewen.Lin via Gcc-patches]

Hi,

On BE, the extracted index for the leftmost element is 0
rather than 1, adjust the test case accordingly.

Tested on powerpc64-linux-gnu P7/P8/P9 and
powerpc64le-linux-gnu P9/P10.

I'm going to push this soon if no objections.

BR,
Kewen
