Do not apply --program-transform-name to build-aux scripts.

autoreconf expects to find $(pkgdatadir)/build-aux/config.sub etc
under those names, not names modified by --program-transform-name.
Placing them in $(pkgdatadir) is sufficient to keep parallel
installations of autoconf separate: anyone doing that would need
to adjust @PACKAGE@ anyway.

* lib/local.mk: Use a _DATA rule, not a _SCRIPTS rule, to install
  config.guess, config.sub, and install-sh.
  (install-data-hook-make-aux-scripts-executable): New hook rule.
