bpf: Initialize ftrace_managed in bpf_trampoline_get()

A trampoline managed by ftrace is determined by its target, that said
ftrace_managed is already known when the trampoline is initialized. so,
set 'ftrace_managed = tr->ip != 0' in bpf_trampoline_get() instead of
relying on the first regular or tracing_multi attachment to set it.

This makes the backend selection independent of attachment order and keeps
the registration callbacks focused on installing the trampoline.

No functional change intended.
