[kdump|release] Change format of imports

[jcastill]

Change the format of the import line for plugins
to parenthesis so it matches what we do in all
other plugins that contain multiline imports.
Also, this change ensures that the script
plugins_overview.py's output is consistent
across all plugins and doesn't contain
errors.
