File timestamps are not preserved when copying files into ZIP archives

[mcoq]

Timestamps atime/mtime are not preserved over extfs.d/uzip copyin action

However, I suppose any other extfs scripts may produce the same behaviour, as a temporary copy of the source file is created in the /tmp/mc-<username> folder, and that file is inserted into the target extfs instance.

The timestamps of the temporary file reflect the time of the copyin action, so the target file in the extfs instance will also differ from the original one.

Opposite to #3916

This affects pretty much all archivers that MC supports including RAR/7z/etc.
