[PATCH] init: show absolute path of (re)initialized repository

[Matt Hunter <m@lfurio.us>]

Since 20e38cba3926 (setup: split up concerns of `init_db()`,
2026-09-10), git-init produces the message:

    Initialized empty Git repository in .git/

instead of the previous

    Initialized empty Git repository in /full/path/to/repo/.git/

Prior to 20e38cba3926, the code producing this message was in function
init_db (renamed at the time to create_repository).  In that context,
the git_dir variable was updated by 'git_dir = repo_get_git_dir(repo);'
earlier in the function, to set the value used in printf.

None of the discussion [1] around the original patch indicates that this
change was intentional, so address the regression by similarly using
repo_get_git_dir in this code's new location.

In this case, git_dir is referencing owned memory that is later freed,
so declare a new variable to hold the used string.
