builtin/am: fold am_signoff() into am_append_signoff()

Browse Source 
There are no more direct calls to am_signoff(), so we can fold its
logic  in am_append_signoff().

(This is done in a separate commit rather than in the previous one, to
make it easier to revert this specific change if additional calls are
ever introduced.)
