tests: Fix no gpg-agent upon removal of GNUPGHOME.
* tests/gpgscm/gnupg.scm (with-ephemeral-home-directory): Add teadown-fn. * tests/gpgsm/export.scm: Use -no-atexit version and stop-agent. * tests/openpgp/decrypt-session-key.scm: Likewise. * tests/openpgp/decrypt-unwrap-verify.scm: Likewise. * tests/openpgp/defs.scm (have-opt-always-trust): Likewise. (setup-environment-no-atexit): New. (start-agent): Support no use of atexit. * tests/gpgsm/gpgsm-defs.scm (setup-gpgsm-environment-no-atexit): New. * tests/migrations/common.scm (untar-armored): Follow the change of with-ephemeral-home-directory.
When gpg-agent detects homedir removal, it will automatically exit.
Then, call of 'gpgconf --kill all' will fail. So, stop-agent should
be called before the removal of homedir.
