[Bug 285394] sysutils/consolekit2 seems to use wrong tty

I've done some additional experimenting and I see why ttyv0 helped me, but was
problematic for other other people.

I have a small customization in /etc/ttys where I disabled getty on ttyv0.
Just in case, my rationale for that is that I keep the first virtual terminal
for kernel / console messages. It would be inconvenient to have a shell session
there as any console messages would interfere with normal output.  So, I just
avoid having getting there.

But I see that having a getty on ttyv0 can cause the same issue as init(8)
caused for /dev/console.  That is, revocation of the terminal device when the
session leader on that terminal / virtual console terminated.

E.g., if I log in on ttyv0 and the logout, I see this:
2025 Apr 29 20:32:16 vgone vnode fffff803fd074000, ttyv0 rdev by login (67940)

              kernel`vgone+0x2f
              kernel`devfs_revoke+0x41
              kernel`VOP_REVOKE_APV+0x71
              kernel`killjobc+0x15a
              kernel`exit1+0x707
              kernel`0xffffffff808bd00d
              kernel`amd64_syscall+0x189
              kernel`0xffffffff80c4fbfb

So, ideally we do need a dedicated character device that could be used for
issuing VT_ ioctls but which would/could not be used as a terminal for any
program.
Internally it could be aliased to ttyv0, all is needed is to have a separate
devfs entry / vnode.
