Merge /proc/kallsyms pointer value restrictions.

Instead of using %pK, and making it about root access (at the wrong
time, no less), make the whole choice of whether to show the actual
pointer value be very explicit to the kallsyms code.

In particular, we can now default to not doing so, and yet avoid
annoying kernel profiling by actually looking at whether kernel
profiling is allowed or not (by default it is not).

This is all mostly preparation for the real "let's stop leaking kernel
addresses" work that Tobin Harding is working on.

Small steps.

* kallsyms-restrictions:
  stop using '%pK' for /proc/kallsyms pointer values
