Thomas Huth 1f4a0d81af tests: Skip old versioned machine types in quick testing mode
The tests that check something for all machine types currently spend
a lot of time checking old machine types (like "pc-i440fx-2.0" for
example). The chances that we find something new there in addition
to checking the latest version of a machine type are pretty low, so
we should not waste the time of the developers by testing this again
and again in the "quick" testing mode.
Thus let's add some code to determine whether we are testing a current
machine type or an old one, and only test the old types if we are
running in "SPEED=slow" mode.
This decreases the testing time quite a bit now, e.g. the qom-test
now finishes within 4 seconds for qemu-system-x86_64 instead of 30
seconds when testing all machines.
