MINOR: cache: Store the "Last-Modified" date in the cache_entry

In order to manage "If-Modified-Since" requests, we need to keep a
reference time for our cache entries (to which the conditional request's
date will be compared).
This reference is either extracted from the "Last-Modified" header, or
the "Date" header, or the reception time of the response (in decreasing
order of priority).
The date values are converted into seconds since epoch in order to ease
comparisons and to limit storage space.
