According to CMakeLists.txt, current faiss doesn't recognize sse4 as FAISS_OPT_LEVEL .
I've read CMakeLists.txts and confirmed that (current faiss treats sse4 as same as generic), so this PR removes the description of this outdated option from INSTALL.md .

This PR contains only document update, so this doesn't affect the software behavior.
