cmake: fix HAVE_IOCTLSOCKET_FIONBIO test with gcc 14

Browse Source 
The function signature has had u_long flags since ever. This is how it
is defined in the documentation, and implemented in MinGW.

The code that uses ioctlsocket in nonblock.c also has unsigned long.

Error:
CurlTests.c:275:41: error: passing argument 3 of 'ioctlsocket' from incompatible pointer type [-Wincompatible-pointer-types]
