tests: Rework environment setup.
* tests/gpgscm/tests.scm (test::scm): Add a setup argument. (test::binary): Likewise. (run-tests-parallel): Remove setup parameter. (run-tests-sequential): Likewise. (make-environment-cache): New function that handles the cache protocol. * tests/gpgme/run-tests.scm: Adapt accordingly. * tests/gpgsm/run-tests.scm: Likewise. * tests/migrations/run-tests.scm: Likewise. * tests/openpgp/run-tests.scm: Likewise.
This change allows us to have different environments for tests. This
is needed to run more GPGME tests, and to increase concurrency while
running all tests.
