[PATCH] builtin.h: remove declaration of cmd_rebase__helper

[Ramsay Jones <ramsay@ramsayjones.plus.com>]

Commit 94d4e2fb88 ("rebase -i: move rebase--helper modes to
rebase--interactive", 2018-07-24) removed the definition of the
'cmd_rebase__helper' symbol, but forgot to remove the corresponding
declaration in the 'builtin.h' header file.

Hi Alban,

If you need to re-roll your 'ag/rebase-i-in-c' branch, could you
please squash this into the relevant patch (commit 94d4e2fb88).

Thanks!

ATB,
Ramsay Jones
