Hi Caleb

This refactors `repair_worktree_after_gitdir_move()` to use the new
`write_worktree_linking_files` function. It also preserves the
relativity of the linking files; e.g., if an existing worktree used
absolute paths then the repaired paths will be absolute (and visa-versa).
It would be helpful to give a brief explanation of what this function is
used for as it seems to be called from setup.c rather than as part of
"git worktree repair"
This also adds a test case for reinitializing a repository that has
relative worktrees.
I'm not sure exactly what this is doing - are we breaking something and
then calling "git init" to repair it?
My understanding of what this function is trying to do is rather limited
but as far as I can see the conversion looks OK though the strbuf
changes are quite distracting.
