default y generally is a big hammer.  But given that it depends on
UPROBES it might be fine here.  Then again the big question is why
we even bother with separate config options?  At least in this form
UPROBES just is supported for UPROBE_EVENT.  So it makes sense either
to remove the UPROBES option entirely, or at least make it invisible
to the user and let UPROBE_EVENT select it.
