bootimg.bbclass:iso: use mkisofs -iso-level 3 for large iso

Browse Source 
There will be problems when rootfs.img is larger than 4GB:
mkisofs: Value too large for defined data type. File /path/to/iso/rootfs.img is too large for current mkisofs settings - ignoring

And will get a wrong iso.

Check the size of ${ISODIR}/rootfs.img, use mkisofs -iso-level 3
when it exceeds 3.8GB, the specification is 4G - 1 bytes, we need
leave a few space for other files.
