aiohttp: Fix header case sensitivity.

According to RFC https://datatracker.ietf.org/doc/html/rfc7230#section-3.2
header names are case-insensitive.

This commit makes sure that the module behaves consistently regardless of
the casing of "Content-type" and "Content-Length" (other headers are not
considered by the module).

Without this fix, the client seems to wait for the connection termination
(~10 seconds) prior to returning any content if the casing of
"Content-Length" is different.
