selftests: net: rebuild YNL if dependencies changed
Try to rebuild YNL if either user added a new family or the specs
of the families have changed. Stanislav's ncdevmem cause a false
positive build failure in NIPA because libynl.a isn't rebuilt
after ethtool is added to YNL_GENS.
Note that sha1sum is already used in other parts of the build system.
