tools/create-image.sh: improve help message

Improve the help message:
- sort options alphabetically
- print default values
- print first line to stdout like the rest of the message
- fix typos, improve style

Also sort the options parsing to be alphabetical (except --help), and use
spaces consistently for indentation in this section.

Log Message:
-----------
tools/create-image.sh: add option to specify output prefix

Add an option, -o / --output, to specify a prefix used for the name of the
directory where debootstrap generates the system, and the final disk image
and SSH key filenames.

The default remains using the distro release codename.

For now, ban the use of slashes, spaces, . and .. as output names.
