core-image-sato-sdk: allocate more memory when in qemu
Compiling code is memory-intensive, especially kernel modules like the
SystemTap probes, so give the VM 768MB of RAM. Using 1GB appears to
cause PCI error, interestingly.
Hopefully this solves the intermittent failures caused by OOMs during
the SystemTap test.
