oeqa selftest wic.py: add TEST_RUNQEMUPARAMS to runqemu

To support "slirp" networking on shared build machines instead
of tun/tap devices. Users can set

TEST_RUNQEMUPARAMS = "slirp"

in their build/conf/local.conf to run selftests using "slirp"
networking. The same works for testimage.bbclass and oeqa runtime
tests.
