ANDROID: lib: vsprintf: additional kernel pointer filtering options
Add the kptr_restrict setting of 3 which results in both
%p and %pK values being replaced by zeros.
Add an additional %pP value inspired by the Grsecurity
option which explicitly whitelists pointers for output.
This patch is based on work by William Roberts
