tools/create-image.sh: add a new option seek
The usage of current create-image.sh:
```
./create-image.sh -d=stretch -f=minimal --add-perf
The options are in the following:
-d, --distribution Set on which debian distribution to create
-f, --feature Check what packages to install in the image, options are minimal, full
-s, --seek Image size (MB), default 2048 (2G)
-p, --add-perf Add perf support with this option enabled
The default image size may too small (2G) in some debugging scenarios, so change it to configurable.
