Change content-type to be always computed from file data (#14452)
* Change content-type to be always computed from file data

Restore previous behavior, detecting the content-type isn't very
expensive, and some instances may serve files as application/octet-stream
regardless of their true type, making fetching media from them fail, while
it used to work pre-3.2.0.

* Add test
