testing: Mount and serve testresults from the host

This avoids having to copy testresults, makes results of cancelled runs
browsable (runs may actually be followed live) and preserves old results
when rebuilding guest images (e.g. when using the build-strongswan script).
The number of consecutive test runs without any intermittent rebuild of the
guest images is also not limited by the image size anymore.
