tests: Add a manifest for system tests.
The manifest can be passed to 'guix build -m', 'guix weather -m', and so on. It can also be passed to an installed 'guix' (without ./pre-inst-env), with the exception so far of installation tests. * build-aux/run-system-tests.scm: Remove. Move interesting bits move to... * etc/system-tests.scm: ... here. New file. * Makefile.am (EXTRA_DIST): Remove 'build-aux/run-system-tests.scm' and add 'etc/system-tests.scm'. (check-system): Rewrite to run 'guix build -m etc/system-tests.scm'.
