These XMLs live in a separate directory, there's no need for them
to have a special prefix in addition. It also doesn't play nicely
with ':e' completion in Vim, finding proper file based on
qemuxml2argvtest.c is also needlessly complicated.

The files were renamed using the following commands. From
qemuxml2argvdata:

  for i in qemuxml2argv-*.xml; do mv $i ${i#qemuxml2argv-}; done

and then (to fix broken symlinks) from qemuxml2argvdata and
qemuxml2xmloutdata:

  for i in $(find . -xtype l); do \
      ln -sf $(readlink $i | sed 's/qemuxml2argv-//') $i;
  done

These tests demonstrate that, while it's now possible for the
user to create PHB explicitly and manually assign devices to
them, libvirt still defaults to extending the guest PCI
topology using PCI bridges and making suboptimal device
placement choices.

The next few commits will improve on these behaviors and the
tests outputs will automatically be updated to reflect this.
