bootstrap: Update package list script

Browse source 
Takes simple options -h (show help), -v (verbose), -n (dry-run) when
started.

By default does not spam output of *all* recognized packages anymore but
simply prints a diff at the end. Old output can be enabled with `-v`
verbose option.

Diff is shown even if dry-run mode is enabled so that using dry-run by
default will show you a preview of what changed.
