bpf: Mark tracing_multi trampolines as ftrace managed

In the Linux kernel, the following vulnerability has been resolved:

bpf: Mark tracing_multi trampolines as ftrace managed

Since tracing_multi link does not set ftrace_managed, it would fail to
release the tracing_multi link when attaching tracing_multi link and
then attaching fentry link.
