oeqa/selftest/imagefeatures: Use QemuTarget code
Create a runqemu function which uses the QemuTarget() code from
oeqa.targetcontrol to setup the QEMU instance, with all of the added
robustness that that gives us. To do this, a datastore is needed for the
recipe in question (core-image-minimal) so we do the work needed to set
this up. We then use this runqemu function within the imagefeatures
tests instead of a hand-rolled implementation.
We can then use SSHControl to run the SSH tests rather than rolling our
own code to do that as an added bonus.
Fixed and extended by Paul Eggleton <paul.eggleton@linux.intel.com>.
Part of the fix for [YOCTO #7994].
