Simplest was just to rename that extra long name and move files in git
accordingly

When cleaning up the data (taken from a running system) for inclusion
I went a little too far and deleted a bunch of links that should have
been left alone. The test worked despite this because it was going
through a fallback code path.

A few other files are affected as well: again, the data is taken from
a running system, so even thought we would probably be okay if we
just added the links, aligning everything is definitely safer.

Some of the possible CPUs in a system might not be present, eg. they
might be defective or might have been deconfigured from the ASM console
in a Power system. Due to this fact, Linux keeps track of what CPUs are
possible and what are present separately.

This test uses the data from a system where not all the possible CPUs
are present to make sure libvirt handles this situation correctly.
