sh: Remove remnants to compile out fc completely

r360139 made compiling with NO_HISTORY work. This #define does not remove
the fc and bind builtins completely but makes them always write an error
message.

However, there was also some code in builtins.def and mkbuiltins to remove
the fc builtin entirely (but not the bind builtin). The additional build
system complication to make this work seems not worth it, so remove that
code.
