bug#56327: Regression: openssh service fails to start if system has no IPv6

Older versions of shepherd are not relevant in this case.

I’ve fixed it slightly differently in commit
bf7e07d299b197891110fbd8c717badbab06a472, to avoid a file descriptor
leak.  Thanks!

Out of curiosity: I suppose you’re explicitly disabling IPv6 by using a
custom kernel or with an activation snippet that fiddles with /proc or
/sys, right?
