Description

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.
