Acceptance tests: use linux-3.6 and set vm memory to 4GiB

QEMU have already supported to load up to 4G initrd if the sepcified memory is
enough and XLF_CAN_BE_LOADED_ABOVE_4G is set by guest kernel

linux-3.6 kernel shipped by Fedora-18 cannot support xldflags so that it
cannot support loading more than 2GiB initrd
