Fix sandbox test failure on some machines

[NicolasFussberger]

//tests/integration/sandbox_options:sandbox_options fails on some machines when run in docker based on whether the underlying linux kernel was built with CONFIG_RT_GROUP_SCHED or not.

The PR introduces the following behavior:

• Check if realtime scheduling is supported in docker container
• If true, run the sandbox test (start docker container with the required parameters)
• If false, fail the test with an error message depicting what to change in host docker config
