Add missing mime4j library

In some cases (apparently with outlook files), mime4j library is needed.
We removed it in the past which can cause elasticsearch to crash when you are using ingest-attachment (and probably mapper-attachments as well in 2.x series) with a file which requires this library.

Backport of #22764 in 5.2 branch

(cherry picked from commit cfef7c5)
