Pass certs and tls config when checking for registry signature extent…

…ions API during

sync

closes #1552

In sync we are checking whether the remot registry implrementations
signsture extentions API. We need to pass respective remote tls and
certs config if they were provided, hence no need to override core's
``_make_aiohttp_session_from_remote`` and use it directly from core.

We do not need to pass auth since we care only about response headers
that we check.

(cherry picked from commit 03c1923)
