Do not rely on the two-argument std::pair constructor being constexpr (#7519)

Browse source 
Summary:
The `std::pair(const T1& x, const T2& y);` constructor is `constexpr`
only starting from C++14; relying on this breaks compilation on certain
compilers/platforms we need to support.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/7519

Test Plan: `make check`
