testimage.bbclass: detect slirp from TEST_RUNQEMUPARAMS

Also set target and server IP addresses correctly to 127.0.0.1
so that TEST_TARGET_IP and TEST_SERVER_IP don't
need to be set manually with slirp.

Users run qemu images with slirp networking like this:

$ bitbake core-image-minimal
$ ../poky/scripts/runqemu slirp

slirp networking means that only one TCP port is forwarded from host
system to the qemu machine so that ssh into the machine works. ping
and other low level networking from host to target machine do not work,
but networking from target via host does work. This is much more easy to
setup than the bridge networking used by default, which I've never
managed to get running on various host machines.

To use slirp networking wita qemu and core-image-minimal to run testimage.bbclass tests, add
these to local.conf:

IMAGE_CLASSES += "testimage"
IMAGE_FEATURES += "ssh-server-dropbear"
TEST_RUNQEMUPARAMS += "slirp"

Then image can be compiled and tested with:

$ bitbake core-image-minimal
$ bitbake -c testimage core-image-minimal

Note that only few of the current oeqa runtime tests work against
core-image-minimal, but test results look like:
