Refactor lib/crypto/gpg tests to facilitate unit test runs on macos.
Macos creates temporary directories with names too long to call
gpg-agent (108 characters). Additionally, too many concurrent test calls
created IPC errors to gpg-agent. To get around this, tests were given
shorter names and refactored into subtests to create fewer concurrent
tests
Tested on Linux and MacOS.
