Drop -c short flag from --config-file to fix click warning

The new --config-file option added in 1c04c47 declared -c as its short
flag, colliding with the long-standing -c/--copyright option from the
copyright scanner plugin. click warns about the duplicate parameter on
every invocation:

    UserWarning: The parameter -c is used more than once. Remove its
    duplicate as parameters should be unique.

Keep -c for --copyright and drop the short flag from --config-file,
which has not shipped in a release yet. Regenerate the help test
fixtures and update the docs pages that embed the help text.
