ssl: workaround for new behavior of SSL_read() in OpenSSL >= 1.1.0c
Commit 4880672a9b41 of OpenSSL[1] (which then was backported to 1.1.0
branch at 122580ef71e4) changed the bahavior of SSL_read(): it now
returns -1 in the case the underlying BIO reaches EOF unexpectedly. This
means, it is possible that rb_sys_fail() is called with errno == 0,
resulting in [BUG].
So, as a workaround, let's distinguish IO error from the underlying BIO
and EOF in violation of SSL/TLS protocol with the value of errno.
