Fix bug #79589: ssl3_read_n:unexpected eof while reading

The unexpected EOF failure was introduced in OpenSSL 3.0 to prevent
truncation attack. However there are many non complaint servers and
it is causing break for many users including those where truncation
attack is not an issue becuase it would break format parsing (e.g.
JSON). we try to keep behavior consitent with older version which
is also the path chosen by some other languages and web servers.

Closes GH-8369
