The dynevent/test_duplicates.tc test case uses `syscalls/sys_enter_openat`
event for defining eprobe on it. Since this `syscalls` events depend on
CONFIG_FTRACE_SYSCALLS=y, if it is not set, the test will fail.
Add the event file to `required` line so that the test will return
`unsupported` result.
Fixes: 297e1dcdca ("selftests/ftrace: Add selftest for testing duplicate eprobes and kprobes")
