[PATCH for-next] selftests/ftrace: Fix required features for VFS type test case

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

Since the VFS type argument test case uses fprobe events, it must
check the availablity of dynamic_events file and fprobe events syntax
in README. Without this fix, the test fails if CONFIG_FPROBE_EVENTS=n.

Fixes: ee97e5e135c6 ("selftests/ftrace: add fprobe test cases for VFS type "%pd" and "%pD"")
