DELVEWHEEL file makes reproducibility difficult

[jvolkman]

The DELVEWHEEL file in dist-info contains the arguments passed to the program at repair time. Various build strategies will use temporary directories which then leak into this file, causing it to not be reproducible across runs.

It might be possible to setup a build environment and pass only relative paths for the input wheel, output directory, and lib paths. But with symlinking being tricky (impossible?) on Windows, that also becomes a difficult task.

It looks like only the Version entry in the file is used at a later time. The Arguments entry is stored but doesn't appear to be ever read again. Would you be open to omitting it, either outright or with some CLI option?

The Arguments entry has been useful in diagnosing issues, so I'd like to keep it. But to support your use case, I added the --no-diagnostic flag.

Can this please be reopened so SOURCE_DATE_EPOCH may be supported? It appears that other patchers support this:

• Add support for SOURCE_DATE_EPOCH pypa/auditwheel#348
• Support for SOURCE_DATE_EPOCH (reproducible builds) matthew-brett/delocate#187

If you want support for SOURCE_DATE_EPOCH, then please open a separate issue.
