selftests/ftrace: Fix ftrace test cases to check unsupported
Since dynamic function tracer can be disabled, set_ftrace_filter
can be disappeared. Test cases which depends on it, must check
whether the set_ftrace_filter exists or not before testing
and if not, return as unsupported.
Also, if the function tracer itself is disabled, we can not
set "function" to current_tracer. Test cases must check it
before testing, and return as unsupported.
