mtime set to 0 on setup.py and PKG-INFO in sdist package

Issue

poetry build creates an sdist tarball. If you unpack that tarball, both the setup.py file and the PKG-INFO file have an mtime of 0. ctime and atime are set properly.

This is clearly visible if you do an ls -al in the unpacked tarball directory. Or you can do stat -c '%X %Y %Z' setup.py.

This should repro with any pyproject.toml but if it doesn't, happy to upload mine.
