Ignore temporary files for directory size

Browse source 
- Backport https://codeberg.org/forgejo/forgejo/pulls/1742
  - While looking trough the logs for unrelated things I noticed errors
for directory size calculations in `pushUpdates` that were being caused
by a race condition in which git was making temporary file,
`filepath.WalkDir` noticed that but by the time the second lstat
came(`info.Info()`) it was already gone and it would error.
  - Ignore temporary files created by Git.
  - There are other cases but much much more rarer and not trivial to detect.

Examples:

...s/repository/push.go:96:pushUpdates() [E] Failed to update size for repository: updateSize: lstat [...]/objects/info/commit-graphs/tmp_graph_Wcy9kR: no such file or directory
...s/repository/push.go:96:pushUpdates() [E] Failed to update size for repository: updateSize: lstat [...]/packed-refs.lock: no such file or directory
