freebsd-update: improve BE creation feature
This addresses one nit and one bug in the BE creation feature of freebsd-update: The nit addressed is that it currently only names the BEs after the userland version, but the kernel version may be higher. After this change, we request both and pass them through sort(1) to choose the highest. This is especially helpful if a freebsd-update patch touched one but not the other. The bug fixed is that roots updated that are not located at '/', e.g., by using -b or -j, will no longer create boot environments automatically. There's a very low chance these will actually change the BE in any meaningful way, anyways. It could make sense in the future to allow an argument-override to create the BE anyways if someone comes up with a non-standard setup, e.g., where a jail is an important part of their boot environment on an appliance or some such setup. Half of this patch is submitted by delphij@, the other half kevans@. PR: 261446 (cherry picked from commit e01e8f911b935eabcc35b4d121951e4e21042ee5)
