Previously, the test suite relied upon creating home directories in
'/tmp'. This has been problematic in some build environments,
although POSIX mandates that '/tmp' must be available.
We now rely on 'gpgconf --create-socketdir' to create a suitable
socket directory for us. This allows us to get rid of some cruft. It
also aligns the environment the tests are run in closer with the
environment that we intend that GnuPG runs in.
