update_engine: Remove rootfs_mountpt from ImageConfig.
The mounted rootfs is not used anymore during opeartions generation so
this patch removes the setting from the ImageConfig. The --new_dir flag
is now deprecated because of this.
The --old_dir is still being used when no --minor_version is passed, to
autodetect the minor version of the old image.
With this patch, the rootfs and kernel partitions have a more generic
description in the config.
BUG=None
TEST=Unittest still pass.
