undo-files: clean existing files up before writing new one
the in the initial design of journal/undo interaction, ages ago, new file always
overwrote previous files. This is no longer the case for a long while, so it is
time to properly clean things up before writing new ones.
Otherwise, inconsistent "undo" state might exist on disk, leading `hg rollback`
to misbehave (more that intended).
