Dev/adelcast/opkg restartcheck support #45554
What does this PR do?
Add NILinuxRT support for the checkrestart module. As part of this PR, I added NILinuxRT support for the service module too, as it is used by the restart module. I also fixed the ps grain definition for NILinuxRT (used by status.pid, which is used in the service module).
Yes. Enabled existing service module tests for NILinuxRT.

The NILinuxRT distribution family uses busybox ps, which doesn't support the -H option. Signed-off-by: Alejandro del Castillo <email@example.com>
