From: Masami Hiramatsu (Google) <mhiramat@kernel.org>

kprobe_args_{char,string}.tc are using available_filter_functions file
which is provided by function tracer. Thus if function tracer is disabled,
these tests are failed on recent kernels because tracefs_create_dir is
not raised events by adding a dynamic event.
Add available_filter_functions to requires line.

Fixes: 7c1130ea5cae ("test: ftrace: Fix kprobe test for eventfs")

Hi Shuah,

Can you pick this? I confirmed this can be applied on v6.11-rc3.
