support/scripts/pkg-stats: add --disable option

When debugging pkg-stats, it's quite useful to be able to disable some
features that are quite long (checking upstream URL, checking latest
version, checking CVE). This commit adds a --disable option, which can
take a comma-separated list of features to disable, such as:

     ./support/scripts/pkg-stats --disable url,upstream
