In the module! macro, the author field is currently of type String.
Since modules can have multiple authors, this limitation prevents
specifying more than one.

- Change the author field to Option<Vec<String>> to allow creating
  modules with multiple authors.

- rename the field from author to authors to make it explicit that it
  can refer to multiple authors.

- In modules that use the author field, update its value to an array of
  strings, and also rename it from author to authors.

- Change the checkpatch.pl to find poorly formatted arrays in the macro
  module!
