oeqa selftest efibootpartition.py: add TEST_RUNQEMUPARAMS to runqemu

TEST_RUNQEMUPARAMS variable is used to add runqemu parameters like
"slirp" networking. Support this also in selftests so that "slirp"
networking can be used instead of the tun/tap devices setup which
is easier to work with on shared build machines.
