x86: Fix overflow bug with wmemchr-sse2 and wmemchr-avx2 [BZ #27974]

This commit fixes the bug mentioned in the previous commit.

The previous implementations of wmemchr in these files relied
on n * sizeof(wchar_t) which was not guranteed by the standard.

The new overflow tests added in the previous commit now
pass (As well as all the other tests).
