Sentry issue: TRIBLER-15C

Actually, after reevaluating the source code of aiohttp/tcp_helpers.py, it may be more likely that the REST API port was blocked (by a firewall).

The error in the stack trace corresponds to a socket that has its access blocked. I can cause a similar (but not the same!) error on the same line by closing the REST API port immediately after opening an initial connection.

For reproduction, I'd recommend using the Mac firewall to block the REST API port that Tribler is using (after starting Tribler initially). Sadly, I (still) don't have a Mac to test this on myself.

From the point of aiohttp, it makes sense to crash here: tcp_keepalive is requested and supported but the given socket cannot apply the tcp_keepalive.

From our point of view, tcp_keepalive is completely optional and Tribler works just fine without it.

Given the internal structure of aiohttp, the only realistic option I see is to wrap tcp_keepalive and catch the error.
