fab9e8a29c2cdeab6cf1ae7c1fc0e0a3af783b17 Remove unused GetTimeSeconds (MacroFake)
Pull request description:
Seems confusing to have this helper when it is possible to get the system time in a type-safe way by simply calling `std::chrono::system_clock::now` (C++11).
This patch replaces `GetTimeSeconds` and removes it:
* in `bitcoin-cli.cpp` by `system_clock`
* in `test/fuzz/fuzz.cpp` by `steady_clock`
