gitweb: add If-Modified-Since handling to git_snapshot().wk/gitweb-snapshot-use-if-modified-since
Because snapshots can be large, you can save some bandwidth by
supporting caching via If-Modified-Since. This patch adds support for
the i-m-s request to git_snapshot() if the requested hash is a commit.
Requests for snapshots of tree-ishes, which lack well defined
timestamps, are still handled as they were before.
