Subject: [PATCH] selftests/sched_ext: fix build after renames in sched_ext API
The selftests are falining to build on current tip of bpf-next and
sched_ext [1]. This has broken BPF CI [2] after merge from upstream.
Use appropriate function names in the selftests according to the
recent changes in the sched_ext API [3].
