akamai: fix signs of from and to GET parameters (elastic#6384)

The initial_interval manifest option is an unsigned interval,
represented as a postive time offset, but the url.params.from template
was adding it unaltered to the now time, resulting in a "from" in the
future. Similarly, the url.params.to template was calculating now less
one minute. Fix the "from" sign and don't offset the "to" time.
