Prevent compilation of frontend-only files in src/common/ with backend

Any frontend-only file of src/common/ should include a protection to
prevent such code to be included in the backend compilation.
fe_memutils.c and restricted_token.c have been doing that, while
file_utils.c (since bf5bb2e) and logging.c (since fc9a62a) forgot it.
