tests: Fix setup of ephemeral home directories.
* tests/openpgp/defs.scm (with-ephemeral-home-directory): Create configuration files when we enter the context. * tests/openpgp/setup.scm: Do not use an ephemeral home directory. Tests should always use the cwd. * tests/gpgsm/setup.scm: Likewise. * tests/gpgsm/export.scm: Add explicit constructor function. * tests/openpgp/decrypt-session-key.scm: Likewise. * tests/openpgp/decrypt-unwrap-verify.scm: Likewise.
Previously, ephemeral homedirectories lacked a configuration, hence
GnuPG tried to start backend daemons using their installed locations.
Fix this by explicitly creating a suitable configuration.
