[ios][disk] IOKit is not available on iOS

[tmm1]

fix iOS builds with cgo trying to build with IOKit

[shirou]

Thank you! I don't know iOS, but IOKit is available on iOS 16.0?

You're right, they include part of IOKit on iOS now.

But the actual drive stats are still macOS only:

https://developer.apple.com/documentation/iokit/kioblockstoragedriverstatisticslatentwritetimekey/

gopsutil/disk/iostat_darwin.c

Line 96 in 360136f

{kIOBlockStorageDriverStatisticsLatentWriteTimeKey, offsetof(DriveStats, writelat)},

Same with the properties:

https://developer.apple.com/documentation/iokit/kiobsdnamekey/

gopsutil/disk/iostat_darwin.c

Line 70 in 360136f

name = (CFStringRef)CFDictionaryGetValue(props, CFSTR(kIOBSDNameKey));

I don't have iOS devices. If it is not possible to build, I would consider this change does not break compatibility. If it breaks, someone will open an issue. so I merge this. Thank you so much!
