[PATCH] Fix a typo in `each_file_in_pack_dir_fn()`'s declaration

[PATCH] Fix a typo in `each_file_in_pack_dir_fn()`'s declaration

One parameter is called `file_pach`. On the face of it, this looks as if
it was supposed to talk about a `path` instead of a `pach`.

However, looking at the way this callback is called, it gets fed the
`d_name` from a directory entry, which provides just the file name, not
the full path. Therefore, let's fix this by calling the parameter
`file_name` instead.

    packfile.h: fix a typo
    
    I stumbled over this typo yesterday. Nothing about this patch is urgent,
    of course, it can easily wait until v2.43.0 is released.

Let's have "packfile.[ch]: " before the title to tell what area the
helper function is about.

Very good observation.  We form a pathname to a file in a
"objects/pack/" subdirectory by concatenating this parameter after
the full_path/full_path_len parameter, which has the path to that
subdirectory, so "file_name" definitely is a much better name.

The "full_path" that does not say full path to what directory may
have room for improvement ("leading_path" or even "packdir"), but
that's OK.

Thanks for spotting.
