revert: prettify fatal messages

Some of the fatal messages printed by revert and cherry-pick look ugly
like the following:

  fatal: Could not open .git/sequencer/todo.: No such file or directory

The culprit here is that these callers of the die_errno() function did not
take it into account that the message string they give to it is followed
by ": <strerror>", hence the message typically should not end with the
full-stop.
