control: fix enabling of all kernel tracepoints and syscalls together

This was accidentally changed in a previous commit when introducing
JUL. Without this fix only all tracepoints were enabled and not all
syscalls when the user selected all Tracepoints and Syscalls in the
enable event dialog box.
