Subject: [PATCH] make build reproducible

we do this by removing the uname usage everywhere: it is not actually
used at runtime at all.

we keep the timestamp, because it is actually used in user_welcome()
but allow it to be overriden.

ideally, that timestamp would be completely removed, but I am not sure
what to put in its place, or if it would break some mysterious RFC (or
client!) if we remove that announcement.
