Alexander Aprelev aa0a4410f4 [vm/certs/win] When adding root certificates consider not_before and not_after properties, only add valid ones.
boringssl seems to be confused when expired certificates are present in trusted root, only picks up the first matching one which could be expired and ignores still-valid-ones.
