package/libopenssl: security bump to v1.1.1g

This fixes CVE-2020-1967:
Server or client applications that call the SSL_check_chain() function during
or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a
result of incorrect handling of the "signature_algorithms_cert" TLS extension.
The crash occurs if an invalid or unrecognised signature algorithm is received
from the peer. This could be exploited by a malicious peer in a Denial of
Service attack. OpenSSL version 1.1.1d, 1.1.1e, and 1.1.1f are affected by this
issue. This issue did not affect OpenSSL versions prior to 1.1.1d.
