x86/loader: Don't update kernel header for CoCo VMs

Update the header makes it different from the original kernel that user
provides via "-kernel", which leads to a different hash and breaks the
attestation, e.g., for TDX.

We already skip it for SEV VMs. Instead of adding another check of
is_tdx_vm() to cover the TDX case, check machine->cgs to cover all the
confidential computing case for x86.
