Hide private entitlements on >= iOS 13.5 (#415)

Browse Source 
iOS 13.5 fixes the psychic paper hack so showing the private entitlement
warning popup is confusing to the user. Additionally iOS 14 checks the
entitlements on installation, so we should not copy the private entitlements
on iOS 14.

Depends on https://github.com/rileytestut/AltSign/pull/15
