elf: Fix tst-cpu-features-cpuinfo for KVM guests on some AMD systems [BZ #28704]

On KVM guests running on some AMD systems, the IBRS feature is reported
as a synthetic feature using the Intel feature, while the cpuinfo entry
keeps the same. Handle that by first checking the presence of the Intel
feature on AMD systems.

Fixes bug 28704.
