sched_ext: Add __weak to fix the build errors

Browse Source 
commit 5cbb302880 ("sched_ext: Rename
scx_bpf_dispatch[_vtime]_from_dsq*() -> scx_bpf_dsq_move[_vtime]*()")
introduced several new functions which caused compilation errors when
compiled with clang.

Let's fix this by adding __weak markers.
