### Please describe the problem.

While running tests on a local HPC with 

```
(datalad) [discovery7 tmp]$ cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)

(datalad) [discovery7 tmp]$ gpgconf --version
gpgconf (GnuPG) 2.0.22
Copyright (C) 2013 Free Software Foundation, Inc.

```

3 tests (also failed in [another more "prolific in fails" run](https://git-annex.branchable.com/bugs/__34__357_out_of_984_tests_failed__34___on_NFS_lustre_mount/) failed due to

```
(datalad) [d31548v@discovery7 tmp]$ grep -B1 FAIL annex-8.20210803-g99bb214-1.log
gpgconf: invalid option "--kill"
FAIL (18.37s)
--
gpgconf: invalid option "--kill"
FAIL (16.43s)
--
gpgconf: invalid option "--kill"
FAIL (17.07s)
```

Not sure if you would like to do anything on git-annex level (skip those tests on outdated etc)...
Meanwhile - adding `gnupg >=2.1.1 ` dependency to conda build: https://github.com/conda-forge/git-annex-feedstock/pull/126
