John Cai 03eae9afb4 builtin: remove USE_THE_REPOSITORY_VARIABLE from builtin.h
Instead of including USE_THE_REPOSITORY_VARIABLE by default on every
builtin, remove it from builtin.h and add it to all the builtins that
include builtin.h (by definition, that means all builtins/*.c).

Also, remove the include statement for repository.h since it gets
brought in through builtin.h.

The next step will be to migrate each builtin
from having to use the_repository.
