lnms dev:check --os-modules-only always

Make --os-modules-only always work.  So if you run as worked before like this to skip os detection tests:
`lnms dev:check unit --os ios --os-modules-only`

Or like this to just test all discovery/polling modules (new):
`lnms dev:check unit --os-modules-only`
