os-win32: drop ffs(3) prototype
The lack of ffs(3) in the MinGW headers is a hint that we shouldn't rely on it. MinGW 4.9.2 does not make it available for linking when QEMU's ./configure --enable-debug is used (release builds are fine though). Now that all QEMU code has been switched to ctz32() there is no need for ffs(3).
