fix path to named-checkconf on FreeBSD/DragonFly BSD

[fraenki]

Fixes the following error:

Error: Execution of '/usr/local/sbin/named-checkconf /usr/local/etc/namedb/zones.conf20250112-57376-i5p19x' returned 1: Error: Could not execute posix command: No such file or directory - /usr/local/sbin/named-checkconf

Turns out the path to named-checkconf is incorrect:

$ uname -o
FreeBSD
$ which named-checkconf
/usr/local/bin/named-checkconf

The test failure does not seem to be related to this PR, the previous test already failed.

Do you happen to know if this change was specific to some FreeBSD version? Right now we only list FreeBSD 11 in our metadata.json which is rather ancient by now.

[fraenki]

@ekohl It seems like this was changed with the introduction of the bind 9.18 port. The bind 9.16 port still installed it into the sbin folder:
https://github.com/freebsd/freebsd-ports/blob/cfada54fb345c0886e2e11f0448bc0f7ed797299/dns/bind916/pkg-plist#L321
So it looks like this was introduced ~3 years ago during the FreeBSD 13.0 lifecycle.

[fraenki]

Should I add FreeBSD 13 and 14 to metadata.json, and remove FreeBSD 11?

[ekohl]

Yes please.

[fraenki]

Done.

[ekohl]

I wanted to change the PR summary to be about the OS version but realized we also only mention DragonFly BSD. Can we safely update that to 6 and does it include bind 9.18? I get the impression they used to ship bind but no longer do, but perhaps I'm just missing something.

[fraenki]

I don't have a DragonFly machine at hand, but they definitely use the same path since about ~3 years:
https://github.com/DragonFlyBSD/DPorts/blob/master/dns/bind918/pkg-plist#L2

So I'd say: let's bump the DragonFly version to 6, too.

[ekohl]

Ah, I couldn't find their ports but that looks correct. Let's bump it to 6 then.
