[libvirt] [PATCH] test_driver: implement virDomainMemoryPeek
Begins by writing a @start byte in the first position of @buffer and
then for every next byte it stores the value of its previous one
incremented by one.
Behaves the same for both supported flags.

Initially I thought about checking whether start+size exceeds the
available physical or virtual memory. However I noticed that even when
I pass -1 as @start the qemu driver doesn't complain and it fills the
buffer with data. So I left it as is, without performing any additional
checks.
