On real IA hardware, neither the ext3 or cpio images are particularly useful
or used. cpio is legacy from initramfs and that specific image now overrides
FSTYPES accordingly. The size difference in filesystems makes ext3 as a file
format less useful, mainly being useful in the qemu case.
When needed users can still override the default FSTYPES so having
saner defaults makes sense. This improves build times and uses less
network bandwidth for builds and releases.
