nodedev: Build a non-loadable driver lib
nodedev: Build a non-loadable driver lib

In order to test the nodedev driver, we need to link against a
non-loadable module. Similar to other loadable modules already in the
repository, create an _impl library that can be linked against the unit
tests and then create a loadable module from that.
