Support for linked git worktrees broken in 1.2.7

[markrian]

🔧 Summary

Running lefthook install in a repository that is a linked worktree (not the main worktree) causes an error like:

$ lefthook install
Error: mkdir /home/markrian/my-linked-repo/home/markrian/my-main-repo/.git/info: no such file or directory

Lefthook version

1.2.7 c88a009

Steps to reproduce

1. In a main worktree (any normal git repo) create a linked worktree e.g., git worktree add ~/path/to/new/repo
2. Change directory to new repo (e.g., ~/path/to/new/repo)
3. Run lefthook install
4. Observe an error like:

$ lefthook install
Error: mkdir /home/markrian/path/to/new/repo/home/markrian/my-main-repo/.git/info: no such file or directory

If you try the same with lefthook 1.2.6, it succeeds without error.

If you run lefthook install from the main worktree, it also succeeds without error.

Expected results

lefthook install should work without error.

Actual results

There's an error.

Possible Solution

I suspect #414 is the source of this breakage, since it adds a mkdir call.
