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).
