ffs: support symbol renaming

[Bruno Haible]

Libraries which use gnulib need to be able to rename symbols, for
namespace cleanliness. This is commonly done through definitions
such as

  #define ffs libfoo_ffs

in <config.h>. But for this to work, the implementation of the gnulib
module must include <config.h>.

        ffs, bcopy, memset: Support symbol renaming via config.h.
        * lib/ffs.c: Include <config.h>.
        * lib/bcopy.c: Likewise.
        * lib/memset.c: Likewise.
