Acceptance tests: expect boot to extract 2GiB+ initrd with linux-v4.16

Browse Source 
XLF_CAN_BE_LOADED_ABOVE_4G is set on vmlinuz shipped by Fedora-28 so that
it's allowed to be loaded below 4 GB address.

timeout is updated to 5 minutes as well since we need more time to load a
large initrd to the guest
