dev-games/libmt_client: port to EAPI 7, install M4 macro, fix libdir

* Fix libdir in our macro (then install it)
* Install M4 macro

This helps consumers like games-board/mt_ncurses_client find
dev-games/libmt_client.

We need to install the M4 macro so that we can actually regenerate
(eautoreconf).

Right now, some	consumers don't	have bundled macros at all,
and others lack the needed libdir fixes.

Let's install fixed ones here (and in libmaitretarot) so that consumers
can just rely on those.
