[FYI] {maint} tests: move runtest.in away from the top-lever directory

[Stefano Lattarini]

Not only this leaves the top-lever directory less cluttered, but
helps in keeping the testsuite-related files more "centralized".

* runtest.in: Move ...
* t/ax/runtest.in: ... here.  While at it, add customary
'@configure_input@' comment line.
* Makefile.am (runtest, EXTRA_DIST): Adjust.
