Don't use all_dependent_configs for sdk frameworks

libs should be propagated to the final binary even without that:
https://gn.googlesource.com/gn/+/master/docs/reference.md#var_libs

But add some missing SDK framework dependencies:

* RTCNativeI420Buffer.mm uses CGBitmapContextGetBytesPerRow.
* socketrocket uses SecCertificateCopyData.
