Remove the Snyk vulnerabilities widget (#211)

The Snyk widget service (snyk-widget.herokuapp.com) has been returning errors
for all libraries for around a year (see #170), with no plan to restore the data
source. Remove it entirely: the get_vulns util, the shield in library_hero, and
the snyk config, so its dead requests can no longer hang or clutter library pages.
