Chuyi Zhou 2e2006c91c sched_ext: Fix the incorrect bpf_list kfunc API in common.bpf.h. 
Now BPF only supports bpf_list_push_{front,back}_impl kfunc, not bpf_list_
push_{front,back}.

This patch fix this issue. Without this patch, if we use bpf_list kfunc
in scx, the BPF verifier would complain:

libbpf: extern (func ksym) 'bpf_list_push_back': not found in kernel or
module BTFs
libbpf: failed to load object 'scx_foo'
libbpf: failed to load BPF skeleton 'scx_foo': -EINVAL

With this patch, the bpf list kfunc will work as expected.
