base: SSL error fetching from github.com via curl

Here's the relevant snippet from a port fetch:

DEBUG: Starting logging for mdbtools @0.9.3_0

error:1407742E:SSL appears all over Google and the Trac here when the client software does not support TLS1.2. I have seen #58934 and #55989. These lead me to believe that an out-of-date (i.e. system) curl is being used to fetch files over HTTPS.

I have the MacPorts curl installed which running manually does not give an SSL error:

$ /opt/local/bin/curl -O https://github.com/mdbtools/mdbtools/releases/download/v0.9.3/mdbtools-0.9.3.tar.gz
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   623  100   623    0     0   1565      0 --:--:-- --:--:-- --:--:--  1573

Whereas:

$ /usr/bin/curl -O https://github.com/mdbtools/mdbtools/releases/download/v0.9.3/mdbtools-0.9.3.tar.gz

curl: (35) error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

I therefore suspect there is some kind of path issue that prevents the MacPorts curl from being used in a fetch operation.
