Add httpry to base::standard-packages

httpry is a tcpdump-like tool oriented to sniffing and showing HTTP
requests. It can be very useful troubleshooting HTTP servers but is
small enough (103K) to be installed across all systems.

Also while we're here, format standard-packages to be one package per
line, for prettier/easily blameable diffs.
