[PATCH 3/3] selftest runtime_test.py: add testimage.bbclass slirp test

[Mikko Rapeli <mikko.rapeli@linaro.org>]

Builds core-image-minimal with testimage.bbclass and an ssh server
and then runs tests with slirp networking. Default test suite must
pass.

With full caches on x86_64 with x86_64 target the test passes in 416 seconds:
