[libvirt] [PATCH] tests: qemuxml2argv: Make tests based on DO_TEST_CAPS_INTERNAL stable

[Peter Krempa]

To avoid problems with test cases specifying an alias machine type which
would change once capabilities for a newer version are added strip all
alias machine types for the DO_TEST_CAPS_INTERNAL based tests.
