Fixed #21219 -- Added a way to set different permission for static files.

Previously, when collecting static files, the files would receive permission
from FILE_UPLOAD_PERMISSIONS. Now, there's an option to give different
permission from uploaded files permission by subclassing any of the static
files storage classes and setting the file_permissions_mode parameter.

Thanks dblack at atlassian.com for the suggestion.
