imagebuilder: allow to specific ROOTFS_PARTSIZE

Setting this options modifies the rootfs size of created images. When
installing a large number of packages it may become necessary to
increase the size to have enough storage.

This option is only useful for supported devices, i.e. with an attached
SD Card or installed on a hard drive.
