tests: Do not run all tests unless in maintainer mode.
* configure.ac: Leak the maintainer mode flag into 'config.h'. * tests/gpgscm/ffi.c: Pass it into the scheme environment. * tests/openpgp/all-tests.scm: Only run tests against non-default configurations (keyring, extended-key-format) in maintainer mode.
Werner is concerned that the tests do take up too much time and asked
me to reduce the runtime of the tests for normal users.
