change get_image_size return type to int64_t

Browse source 
Previously, if the size of initrd >=2G, qemu exits with error:
root@haswell-OptiPlex-9020:/home/lizj# /home/lizhijian/lkp/qemu-colo/x86_64-softmmu/qemu-system-x86_64 -kernel ./vmlinuz-4.16.0-rc4 -initrd large.cgz -nographic
qemu: error reading initrd large.cgz: No such file or directory
root@haswell-OptiPlex-9020:/home/lizj# du -sh large.cgz
2.5G	large.cgz

this patch changes the caller side that use this function to calculate
size of initrd file as well.
