Use windows pipe open and close on win32

Following the pattern found here: https://github.com/libproxy/libproxy/blob/d6990f4aaab4b947a490ab1abfd9ac6e62d66d7a/libproxy/url.cpp#L23, This commit uses the _popen and _pclose functions from windows `stdio.h` (included in the existing code via `<cstdio>` on windows builds).
