[PATCH 1/3] rust: module: change author to be a array

[Guilherme Giacomo Simoes <trintaeoitogc@gmail.com>]

In the module! macro, the author field has a string type. Once that the
modules can has more than one author, this is impossible in the current
scenary.
Change the author field for accept a array string type and enable module
creations with more than one author.
