oeqa/runtime/apt dnf opkg: support running from within docker container
If the user specified an http port to use for serving
files, use that instead of a random one. At the same
time, have the http server bind to all interfaces.
Binding to the server_ip might not always be possible,
e.g. in the case of running bitbake / oeqa from within
a docker container. In this case, the ip address is valid
outside the container, but not inside, and hence can't
be bound to. So switch to simply binding to all interfaces.
