Fix advertised dispsize for libpq's sslmode connection parameter.

"8" was correct back when "disable" was the longest allowed value, but
since "verify-full" was added, it should be "12".  Given the lack of
complaints, I wouldn't be surprised if nobody is actually using these
values ... but still, if they're in the API, they should be right.

Noticed while pursuing a different problem.  It's been wrong for quite
a long time, so back-patch to all supported branches.
