tests/gnupg: Work around possible buffering issue
Recently the test has started to stall, so I investigated and found the commit that introduced this in nixpkgs[1]. The commit in question changes the command to be passed to Machine.execute from a list in a subshell environment (like "(some commands)") to using a subshell directly via "sh -c". This is allegedly to avoid shell injection, but what matters in our case I guess is that it forks into another shell. Unfortunately, I did not find out *exactly* why this happens but it seems to affect buffering in such a way that the command never terminates for some reason. Since I don't have a lot of time to investigate further, I just worked around the issue by suppressing stdout output from the expect scripts we run. This is not nice but since the test stall is irrelevant to our gnupg module, it doesn't make sense to block the test for reasons out of the scope of this test.
