archival: add "extended-timestamp" extra block for zip archives (issue3600)

Before this patch, zip archives created by "hg archive" are extracted
with unexpected timestamp, if TZ is not configured as GMT.

This patch adds "extended-timestamp" extra block to zip archives, and
unzip will extract such archives with timestamp specified in added
extra block, even though TZ is not configured as GMT.

Please see documents below for detail about specification of zip file
format and "extended-timestamp" extra block:

Original implementation of this patch was suggested by "Jun Omae
<[e-mail]>".
