configure: detect getsockname and getpeername on windows too
Made detection macros for these two functions in the same style as other functions possibly in winsock in the hope this will work better to detect these functions when cross-compiling for Windows. Follow-up to e91e4816123 Fixes #3913 Closes #3915
