testsuite: aarch64: Fix failing SVE tests on big endian

[Jonathan Wright via Gcc-patches]

Hi,

A recent change "gcc: Add vec_select -> subreg RTL simplification"
updated the expected test results for SVE extraction tests. The new
result should only have been changed for little endian. This patch
restores the old expected result for big endian.

Ok for master?

Thanks,
Jonathan
