Some changes for mountimage tool

• If no mount for / (root) at given mount point can be established before mounting a sub partition, a virtual mountpoint with small tmpfs (ramdisk) is set up for / (root), so also non hierarchical images without a root partition can be set up. This is usable, if partitions of an image are not related to each other. Unmounting the image automatically removes the ram disk.
• Some error corrections like logging function instead of echo.
• Some sleep 1 is needed after partprobe, because other tools to get labels and other partitions sometimes work on useless info of device.
