mapconcat fast path with `identity` function argument
This makes (mapconcat #'identity SEQ) slightly faster than
(apply #'concat SEQ), which used to be much faster.
Notably, `string-join` benefits from this change as it uses mapconcat.
* src/fns.c (Fmapconcat): Speed up execution when the function
argument is `identity`.
