lib/bbitset.h code cleanup for C89

[Paul Eggert]

While fixing something else, I noticed that bbitset.h includes
limits.h conditionally.  We've been assuming C89 for some time now in
the bitset code, so I installed this minor code cleanup.

        * lib/bbitset.h: Include <limits.h> unconditionally.  We have been
        assuming at least C89 in the bitset code for some time now.
