iOS: Remove availability checks for versions below the 15.0 minimum

Also drops what they guarded: the pre-14 UIImagePickerController and
document picker fallbacks, the psychic paper entitlement workaround
(fixed in 13.5), and the CS_EXECSEG_ALLOW_UNSIGNED JIT probe, which
returned false on everything from 14.4 on.
