main/openrc: add support for nested network configs

Add support for source and source-directory keywords in network
configuration by use ifquery from ifupdown-ng. Use a fallback for
busybox ifupdown in case ifquery is not available.

Run the `make check` to run unit tests in openrc.

Also add some unit tests for the find_ifaces and find_running_ifaces
functions in networking.initd.

fixes #11562
