support/scripts/pkg-stats: add -v/--verbose option

Running pkg-stats is currently quite verbose, as it shows one line per
package when checking for the upstream URL, and another one line per
package when checking for the latest version on
release-monitoring.org.

This noisy output is a bit annoying when pkg-stats is run in a
cronjob, like we do to update https://autobuild.buildroot.net/stats/
every day. This commit adds a -v/--verbose option, off by default, to
have a less noisy output.
