Provide the right fix for the kvm_extra parameter
With the previous adjustment the arguments were boxed into one extraarray. This actually makes the parameter work (with the same caveats).
The manpage is also updated with the limitations.

kvm: don't pass whole extra as a single argument
If extra is longer than a single word passing it the way it was passedwon't work. Of course this solution is also only partial, as won't takeinto account any form of quoting. :/

These options allow to specify whole instance policy specs. This is neededfor the upcoming changes that tend to threat specs as monolithic objects.
