- Change example qemu-ifup script to not depend on bridge-utils.
Also update the paths used for ip binary.

- Eliminate bogus use of CPUID_7_0_EDX_PRED_CMD which we've
carried since the initial Spectre v2 patch was added. EDX bit
27 of CPUID Leaf 07H, Sub-leaf 0 provides status on STIBP, and
not the PRED_CMD MSR. Exposing the STIBP CPUID feature bit to the
guest is wrong in general, since the VM doesn't directly control
the scheduling of physical hyperthreads. This is left strictly to
the L0 hypervisor.
