[PATCH bpf-next 2/4] bpf: Warn on non-preallocated case for missed trace types

[Yafang Shao <laoar.shao@xxxxxxxxx>]

BPF_PROG_TYPE_RAW_TRACEPOINT_WRITABLE and BPF_PROG_TYPE_TRACING are
trace type as well, which may also cause unexpected memory allocation if
we set BPF_F_NO_PREALLOC.
Let's also warn on both of them.
