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 (https://github.com/facebookresearch/faiss/issues/3218).
