common/utils.h: add tal_arr_expand helper.

Browse Source 
We do this a lot, and had boutique helpers in various places.  So add
a more generic one; for convenience it returns a pointer to the new
end element.

I prefer the name tal_arr_expand to tal_arr_append, since it's up to
the caller to populate the new array entry.
