Description of Linked Ticket

getBuildInfo() on a mac currently returns only `macOS` without specifics about the version. It would be able to detect quirks (such as TLS handling on 10.15+) during jstests, so add the version to the build info output.

It appears we can use sysctlbyname to pull this information, something like:
 

char buffer[64];
size_t buffer_len = sizeof(buffer) - 1;
sysctlbyname("kern.osproductversion", buffer, &buffer_len, nullptr, 0);
buffer[buffer_len] = 0;
