evolve: import mercurial.node as nodemod

Makes it easier to do e.g. debugging in functions that uses `node` as a
variable name.

For the record, variable named `node` is used 5 times in this file.
mercurial.node module is used in 4 cases seen in this patch and 2 of them
already can be written without using `node` (nullid is imported directly).
