[PATCH 3/6] test: add 'GnuPG' prereq to dependent 'crypto' tests

[Thomas Jost]

From: Pieter Praet <pieter at praet.org>

Adds a new test that checks for the presence of 'gpg',
and adds that test as a prereq to all subsequent tests
that rely on GnuPG.

This causes tests with unmet dependencies to be skipped.
