Subject: [PATCH] selftests/ftrace: Test toplevel-enable for instance

'available_events' is actually not required by
'test.d/event/toplevel-enable.tc' and its Existence has been tested in
'test.d/00basic/basic4.tc'.

So the require of 'available_events' can be dropped and then we can add
'instance' flag to test 'test.d/event/toplevel-enable.tc' for instance.

Test result show as below:
 # ./ftracetest test.d/event/toplevel-enable.tc
 === Ftrace unit tests ===
 [1] event tracing - enable/disable with top level files [PASS]
 [2] (instance)  event tracing - enable/disable with top level files [PASS]

 # of passed:  2
 # of failed:  0
 # of unresolved:  0
 # of untested:  0
 # of unsupported:  0
 # of xfailed:  0
 # of undefined(test bug):  0
