tests: Adjust to SRFI-64 as found in Guile 3.0.7. In Guile 3.0.7, 'test-runner-current' is set to #f upon 'test-end'. Consequently, the previous strategy, where we'd call 'test-runner-current' after 'test-end', no longer works. Instead, set the test runner in each test right before 'test-begin'. * gnu/build/marionette.scm (system-test-runner): New procedure. * gnu/tests/audio.scm (run-mpd-test): Replace (exit (= ...)) idiom by (test-runner-current (system-test-runner)). * gnu/tests/base.scm (run-basic-test) (run-cleanup-test, run-mcron-test, run-nss-mdns-test): Likewise. * gnu/tests/ci.scm (run-laminar-test): Likewise. * gnu/tests/cups.scm (run-cups-test): Likewise. * gnu/tests/databases.scm (run-memcached-test) (run-postgresql-test, run-mysql-test): Likewise. * gnu/tests/desktop.scm (run-elogind-test): Likewise. * gnu/tests/dict.scm (run-dicod-test): Likewise. * gnu/tests/docker.scm (run-docker-test): Likewise.
