Error adding system routes

[jgallagher]

Within the switch zone on madrid, we observed that even though magehemite had found prefixes for peers (unknown here is actually the hostname of the peer):

root@oxz_switch:~# /opt/oxide/mg-ddm/bin/ddmadm get-prefixes
Destination              Next Hop                  Path
fdb0:a840:2504:355::/64  fe80::aa40:25ff:fe04:355  BRM44220001
fdb0:a840:2504:157::/64  fe80::aa40:25ff:fe04:157  unknown

there were no routes set up:

root@oxz_switch:~# /opt/oxide/dendrite/bin/swadm route list
Subnet                                      Port   Link Gateway
root@oxz_switch:~#

@rcgoodfellow noted this in the mg-ddm logs that indicates the culprit:

@jgallagher I believe the ddmd build from #58 should fix this.

@rcgoodfellow Using the ddmd build from #58 with the latest omicron main dendrite commit (963bcd784e4385cbb45ecfba548ac4b1abb6edc1, which per @internet-diglett matches 8067c39088482ada72b005cb394270815d181bee), I'm seeing a different error in the mg-ddm logs:

Ah i see, sorry, one moment ....

@jgallagher I believe I've fixed this - if your lap times are long in trying these changes out, I can spin up my ddmd/dendrite development environment and run this through tests.
