Add a guard for SSE 4.2 feature

[Watson1978]

On platform using ARM CPU such as Apple M1/M2, it causes build error (see below logs) with --with-sse42.
So this patch adds a guard for Apple M1/M2.

$ gem install pkg/oj-3.14.0.gem -- --with-sse42
Building native extensions with: '--with-sse42'
This could take a while...
