Noah Goldstein b2c474f8de x86: Fix strncat-avx2.S reading past length [BZ #30065] 
Occurs when `src` has no null-term.

Two cases:

1) Zero-length check is doing:
```
    test    %rdx, %rdx
    jl      L(zero_len)
```
which doesn't actually check zero (was at some point `decq` and the
flag never got updated).

The fix is just make the flag `jle` i.e:
```
    test    %rdx, %rdx
    jle     L(zero_len)
```

2) Length check in page-cross case checking if we should continue is
doing:
```
    cmpq    %r8, %rdx
    jb      L(page_cross_small)
```
which means we will continue searching for null-term if length ends at
the end of a page and there was no null-term in `src`.

The fix is to make the flag:
```
    cmpq    %r8, %rdx
    jbe     L(page_cross_small)
```
