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).
