Enable the new growfs_postboot mechanism. Note that this also implies disabling automatic allocation of swap space on the root disk, since we cannot grow the root filesystem if swap space is allocated after it. This will not be MFCed since it is a significant behavioural change. Sponsored by: Amazon Relnotes: yes
