oeqa/target/ssh oeqa/target/qemu: expose server listening port to tests

Allow tests to access the listening port as just introduced.
Note that when using qemu this infrastructure shouldn't be
needed, but we still need to set the port to 0 so that
a listening port is determined automatically (e.g. by the
python http server).
