Subject: [PATCH] fix the mongodb install issues on 2.7.0

See also: https://github.com/unofficial-unifi/unifi-pfsense/issues/320#issuecomment-1646732257,
but TL;DR:

- pfSense 2.7.0 forked off from FreeBSD 14.0-pre at some time N
- FreeBSD 14.0-pre switched to OpenSSL 3.0 in base at some time N+1
- we pull from `FreeBSD:14:x` "latest" here
- thus "latest" expects OpenSSL 3.0, but we (pfSense) have a base with
  OpenSSL 1.x

Thus, mongodb from FreeBSD:14:x errors out with missing `libssl.so.30`
linking errors.

https://github.com/pfsense/FreeBSD-src/commit/b077aed33b7b6aefca7b17ddb250cf521f938613
says that we're gonna get OpenSSL 3.0 *eventually* in pfSense, but for
now, we can pull from FreeBSD:13:x if we see that bad combination of
`(abi, pfSense version)`.
