defaultUnpack: Preserve timestamps when copying files
Commit 6d928ab684327e0eeb1bf6cd889d57ca7127e8a7 changed this to not preserve timestamps. However, that results in non-determinism; in particular, it gives us a broken $SOURCE_DATE_EPOCH (especially for everything using fetchFromGitHub). Builds affected by timestamps < 1980 should be fixed in some other way (e.g. changing the timestamp to some fixed date > 1980).
