scripts/pre-commit: Auto-generate keys when needed

Generate unique keys for YAML project files lacking them.

There are two minor issues left:
  1. Due to the "git add", not only the key is added to the file,
     but also any other changes that are not yet staged,
  2. When doing "git add <file>; git commit <file>", the addition of
     the key is also left in the unstaged changes as a side effect,
     so "git diff" still shows that change as uncommitted.
     More investigation shows this only happens when passing the
     file name to the "git commit" command.  Hence it does not
     happen when doing "git add <file>; git commit".
