freebsd-vm-image: also DHCP re0

Two comments:

• You can get equivalent functionality by setting ifconfig_DEFAULT=SYNCDHCP in rc.conf.
• If I recall correctly, setting this causes some spurious test failures. I'm not sure if that's the case. Did you successfully run the test suite on amd64 with this change?

I tried the ifconfig_DEFAULT=SYNCDHCP approach and kept getting log messages like this:

Apr  8 10:55:29 freebsd dhclient[77280]: lagg0: not found
Apr  8 10:55:05 freebsd dhclient[54840]: vmnet0: not found
...

This happens constantly across all tests that spin up interfaces.

Right, devd is spinning up dhclient instances each time a test creates an interface, I guess.

What interface gets created with RVVM? I know it's hacky, but for now I slightly prefer to just hardcode that interface name too, instead of putting extra magic into rc.local that might be surprising later.

It seems to be re0, although it might be different on your system if your host doesn't have an re0 when invoking RVVM.
