The modifications based on the following commits are made by the way:
- seloader: Fix building for rocko (bc6bbe2)
- meta-integrity: rpm: Add back in required patches for rocko (5fa9c85)
Because the sanity check for rocko now becomes unnecessary.
In addition, the meta-intel-sgx is removed because it is still
experimental.
- meta-intel-sgx: Initial support of linux-sgx-driver (7d4f711)
