selftests/ftrace: Fix BTFARG testcase to check fprobe is enabled correctly
...
Since the dynevent/add_remove_btfarg.tc test case forgets to ensure that
fprobe is enabled for some structure field access tests which uses the
fprobe, it fails if CONFIG_FPROBE=n or CONFIG_FPROBE_EVENTS=n.
Fixes it to ensure the fprobe events are supported.
