Generate the certificate to be used for koji in make-certs.sh by
the same CA that also generates the composer and client certs.
Create a single certificate that uses the SubjectAltName (SAN)
extension to cover two domains: localhost, org.osbuild.koji.koji,
which previously was done via two separate certificates; this is
the legacy usage which stopped working with go 1.15 (see previous
commit). As a consequence the apache config is modified to use
only one virtual host with a ServerAlias directive.
Rework the generation of certificates, in order to make use of
the SubjectAltName (SAN) extension, that is required for modern
usage of TLS (see RFC 2818, or [1]) and now enforced by default
for go version 1.15[2] (Fedora 33). For this a different config
file is used, originally written by Lars, and assign SANs to
the server and client certificates. Additionally, the correct
extensions are used for each of those, so that their usage is
limited to the server or client use case. The client certificate
is renamed from "worker" to "client".
The lifetime of the certificates is increased, as a side effect of
the new config file.

Move the container directory, containing the container definitions
for all the test containers, to test/, where all the other test-
related files are located (with the exception of `Schutzbot`).
Use `test/build-container.sh` to build the container, instead of
replicating that in `test-integration.sh`.
