Add notBefore and notAfter to SSL cert info display

This adds the X509 attributes notBefore and notAfter to sslinfo
as well as pg_stat_ssl to allow verifying and identifying the
validity period of the current client certificate. OpenSSL has
APIs for extracting notAfter and notBefore, but they are only
supported in recent versions so we have to calculate the dates
by hand in order to make this work for the older versions of
OpenSSL that we still support.

Original patch by Cary Huang with additional hacking by Jacob
and myself.

plover running OpenBSD 6.9 is unhappy since apparently LibreSSL only added ASN
time diffing in the OpenBSD 7.1 release. Version 6.9 is out of support from
OpenBSD with 7.4 being the latest (they support 2 releases), but I guess we are
more forgiving in what we support? (We have only defined a minimum supported
version of OpenSSL, we should do the same for LibreSSL since it's right now
unclear what we support and for how long.) Adding checks for symbol existence
in autoconf/meson seems like the only way forward for now.

Yeah... were you thinking we'd just return a zero timestamptz and let
those columns be NULL?

I don't think we have any other options really.

For now I will revert this to make the buildfarm green again.
