Pavel Hrdina 6ff69e936e tests: introduce hugepages-default-1G-nodeset-2M
This test case is currently working but it uncovers existing issue
in our code that the generated QEMU commandline uses the default 1G
hugepage instead of the 2M hugepage specified for exact node.

The issue in our code is that for non-numa guests we take into account
only the first hugepage.  This will be fixed as invalid configuration
since it doesn't make any sense to set default and specific hugepage
for non-numa guest.
