KVM: selftests: Add additional pages to the guest to accommodate ucall
Add additional pages to the guest to account for the number of pages the ucall headers need. The only reason things worked before is the ucall headers are fairly small. If they were ever to increase in size the guest could run out of memory. This is done in preparation for adding string formatting options to the guest through the ucall framework which increases the size of the ucall headers.
