simple: Invoke __COMPAT_scx_bpf_switch_all();

Browse Source 
scx_simple no longer supports running in "partial" mode, with only
certain tasks usig scx_simple. When this option was removed, we also
removed the call to scx_bpf_switch_all();

While switching-all is the default behavior for newer kernels, let's add
__COMPAT_scx_bpf_switch_all() so that scx_simple can work on older
kernels as well.
