[PATCH v2 3/3] apt: add apt selftest to test signed package feeds

["Ferry Toth" <fntoth@gmail.com>]

From: Ferry Toth <ftoth@exalondelft.nl>

Since Gatesgarth apt (1.8.2) has become more strict and doesn’t allow unsigned repositories by default.
Currently when building images this requirement is worked around by using [allow-insecure=yes] and
equivalently when performing selftest.

Patches "gpg-sign: Add parameters to gpg signature function" and "package_manager: sign DEB package feeds"
enable signed DEB package feeds. This patch adds a runtime test for apt derived from the test_testimage_dnf
test. It creates a signed deb package feed, runs a qemu image to install the key and performs some package
management. To be able to install the key the gnupg package is added to the testimage.
