Olof Johansson 352fd90e51 build: Truncate timestamps in zip archive
Even though zip's -X flag suggests that it removes timestamps, that's not
quite true. There's still modification times per file, and that introduces
non-determinism that are hard to notice, since the mtimes are unlikely to
change without changes to the files. Only when doing a new clone/unpacking
a tar ball under some circumstances or similar action that resets/discards
the mtimes, we would notice.

So, the -X is not enough, and from what I can tell, there's no way of
telling zip to not include timestamps (or truncate them). With this
change, we stage all files in a temporary .build directory, and set the
mtime manually to the beginning of time (as is the case for zip files:
1980-01-01T00:00). These timestamps should not be important to anyone,
since they are all presented to the user as a blob.

The rationale for this change is that this makes it possible to build
svtplay-dl reproducibly. And it also removes the pesky svtplay-dl diffs
just from regenerating the executable.
