Make the daily report test header href to the graph will all notable machines.

In cases where the same test has shown a delta across multiple machines,
it is sometimes useful to have a graph with all of them plotted to help
figure out whether the deltas are related. This commit augments the
result table per-test header rows with a link to the relevant graph
containing all machines in subsequent rows.
