This patch series introduces changes to add default build support for
the sched tests in selftests.

The only test under sched is cs_prctl_test which validates cookies when
core scheduling is in effect. This test fails on systems where core
scheduling is disabled. The patch series also modifies this behaviour to
gracefully skip the test on such systems.

A system with core scheduling disabled would skip the test like:
~# ./run_kselftest.sh
TAP version 13
1..1
 timeout set to 45
 selftests: sched: cs_prctl_test
 prctl failed: Invalid argument
 Core sched not supported, hence skipping tests
ok 1 selftests: sched: cs_prctl_test # SKIP
