DM_UEVENT toggles uevents on or off across the whole of device-mapper.

If there is no particular need for verity *not* to generate uevents
while other parts of device-mapper *are* generating them, then we can
make do with just the one Kconfig parameter.  (Userspace is still free
to ignore particular events.)

So let's drop the second config parameter.
