resize and mount partitions for 3parts target

scripts/tv-mbr-3parts has three partitions - rootfs, system-data, and user.
/etc/fstab installed by setup package has only a root(/) mount entry.
So, /etc/fstab should be modified to mount the other partitions
for a target which use tv-mbr-3parts scripts.

And, the size of a file system image is not the same as the size of a real partition
on a target. resize2fs should be executed at the firt boot time to fit for the size.

* TODO:
A resize2fs@service file is created in tv-mbr-3parts.post script.
The file should be installed by a package later.
