rgw: enforce Content-Type in Swift responses.

Swift sends Content-Type HTTP header even if the response
doesn't contain body. We have this behaviour implemented
until applying some changes in end_header() function.
Unfortunately, lack of Content-Type causes early exits in
many Tempest's tests for Swift API verification.

Fixes: #12157
