[Buildroot] [git commit branch/2019.02.x] board/ci20/genimage.cfg: drop hardcoded rootfs partition size

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=7ff9a16e6ef8894559f9cb8b6f4624b9dfffe3b6
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.02.x

As recently reported to the list:
http://lists.busybox.net/pipermail/buildroot/2020-January/271937.html

The hardcoded rootfs partition size can lead to hard to understand build
failures if more packages are added.

So drop the hardcoded partition size.  Genimage will then size the partition
to match the size of the rootfs image (which by default is also 60MB for ext4).
