internal/report, etc.: speed up setting published date

Rather than checking the commit history for each report's file
individually (which internally involves walking the complete repo
history), walk the history once and build a table of modification
times for each file of interest.

This changes the time to set all dates on my laptop to from about
two minutes to about two seconds.
