build: move automake and aclocal in 'bin' subdir

* automake.in: Rename ...
* bin/automake.in: ... like this.
* aclocal.in: Rename ...
* bin/aclocal.in: ... like this.
* Makefile.am: Move parts that dealt with the building/distribution
of aclocal and Automake ..
* bin/Makefile.inc): ... in this new included fragment.  Adjust as
needed, and make deliberate use of the '%D%' substitution.
* lib/gen-perl-protos: Move ...
* bin/gen-perl-protos: ... here.
* bootstrap.sh, configure.ac, maintainer/rename-tests,
t/wrap/aclocal.in, t/wrap/automake.in, doc/Makefile.inc,
t/ax/tap-setup.sh, .gitignore: Adjust.
* maintainer/syntax-checks.mk: Likewise, and enhance a little.
