Some chore fixes (#4010)

Summary:
- Fix a typo in comment
- Add missing header files to `FAISS_HEADERS` in CMake config

There should be some check against the inconsistency between `FAISS_HEADERS` and actual files, e.g. test compiling with installed headers and shared library (otherwise it always succeeds in the source dir).

This is not the first time that headers are missing (#3218).
