Installing Sage's python3 spkg produces some untracked files

Steps To Reproduce

Run ./configure --with-system-python3=no; make python3. This is with Sage 10.3.beta4 on OS X.

Expected Behavior

This should succeed, leaving a clean git state.

Actual Behavior

git status returns

On branch develop
Your branch is up to date with 'upstream/develop'.

Untracked files:
  (use "git add <file>..." to include in what will be committed)
    build/pkgs/python3/spkg-legacy-uninstall.log
    build/pkgs/python3/spkg-legacy-uninstall.time

nothing added to commit but untracked files present (use "git add" to track)

Additional Information

Probably the log files should be in logs/pkgs, maybe called python3-spkg-legacy-uninstall.* in case there could be other spkg-legacy-uninstall scripts that might produce log files.

Environment

- **OS**: OS X 14.4.1
- **Sage Version**: 10.3.beta4
