Rather than remove the flag entirely, as proposed in facebook#3499, this commit uses the newest C++ standard the compiler supports. This retains the selection of using only standardized features (excluding GNU extensions) and keeps the recency requirements of the codebase explicit. Tested with various versions of `g++` and `clang++`.

What benefit is there in selecting a C++ standard newer than C++11 ? |
|
As noted in #3499, newer gtest versions require >=C++14 (and pzstd tries to find a system-installed gtest for its tests). |
