build: Move environment '.in' scripts to 'build-aux' directory.

* pre-inst-env.in: Move to ...
* build-aux/pre-inst-env.in: ... here.
* test-env.in: Move to ...
* build-aux/test-env.in: ... here.
* configure.ac (AC_CONFIG_FILES): Adapt to this.  Keep the generated
scripts in their current location which is $(top_builddir).

+# so that Guile's 'relative' %file-port-name-canonicalization can actually
+# work (see <http://bugs.gnu.org/17935>.)
