fix: Remove S3_COURSE_IMPORT_EXPORT_BUCKET

In upstream openedx-platform, if COURSE_IMPORT_EXPORT_BUCKET is set,
COURSE_IMPORT_EXPORT_STORAGE will be set to ImportExportS3Storage
which is a subclass of S3BotoStorage
(https://github.com/edx/edx-platform/blob/master/cms/envs/production.py#L340).
S3BotoStorage will break for Python versions >= 3.4.4
(see boto/boto#3433).
Therefor we remove the COURSE_IMPORT_EXPORT_BUCKET parameter until
this is fixed in upstream edx-platform.
