Cygwin: Fix warnings about narrowing conversions of socket ioctls

Fix gcc 12 warnings about narrowing conversions of socket ioctl constants when used as case labels, e.g: > ../../../../src/winsup/cygwin/net.cc: In function ‘int get_ifconf(ifconf*, int)’: > ../../../../src/winsup/cygwin/net.cc:1940:18: error: narrowing conversion of ‘2152756069’ from ‘long int’ to ‘int’ [-Wnarrowing] Signed-off-by: Jon Turney <[email protected]>
