docs: List all possible absolute pathes for the given module.
  
  @param {string} moduleName - Name of the module (with dots).
  @param {array} srcPath - Array of absolute pathes where to look for sources.
  Module's files lie in the subdirectory `mod/` of a source directory.
  @returns {array} Array of absolute module pathes in order of preferrence.
  Because a module can be made of several different files with the same basename,
  These pathes have no file extension.
