Subject: amd64/bn_arch.h: avoid redefinition of `OPENSSL_NO_ASM`

Fixes this warning when `OPENSSL_NO_ASM` is already set by the build
system (seen with CMake):
```
In file included from ./libressl/crypto/bn/bn_mul.c:65:
./libressl/crypto/bn/arch/amd64/bn_arch.h:24:9: warning: 'OPENSSL_NO_ASM' macro redefined [-Wmacro-redefined]
        ^
<command line>:10:9: note: previous definition is here
        ^
```

Reported in #910
