CMake: Revise tuklib_use_system_extensions

Browse Source 
Define NetBSD and Darwin/macOS feature test macros. Autoconf defines
these too (and a few others).

Define the macros on Windows except with MSVC. The _GNU_SOURCE macro
makes a difference with mingw-w64.

Use a function instead of a macro. Don't take the TARGET_OR_ALL argument
because there's always global effect because the global variable
CMAKE_REQUIRED_DEFINITIONS is modified.
