selftests/ftrace: Return unsupported if no error_log file



commit 619ee76f5c9f6a1d601d1a056a454d62bf676ae4 upstream.

Check whether error_log file exists in tracing/error_log testcase
and return UNSUPPORTED if no error_log file.

This can happen if we run the ftracetest on the older stable
kernel.
