Instance property used to get network.carrier has been deprecated

[gideonkylejeffrey]

In checking for my own purposes how Segment populates network.carrier, I found that the instance property used in

analytics-ios/Segment/Internal/SEGUtils.m

Line 368 in e35f1c9

CTCarrier *carrier = [_telephonyNetworkInfo subscriberCellularProvider];

- that is, subscriberCellularProvider - has been deprecated.

See documentation at https://developer.apple.com/documentation/coretelephony/cttelephonynetworkinfo/1616900-subscribercellularprovider (Apple recommends using serviceSubscriberCellularProviders instead).

Xcode organiser highlights this trace as contributing to the slow app launch as well.
please prioritise adding conditional compilation to this block to limit it only to the supporting iOS versions as rest just returns irrelevant string
