Description: Remove privacy breaching Google icons in favor of fork in Debian
 The docs make use of Google's Material icons, but calls to external sites are
 not acceptable in offline doc packages, and trigger Lintian's privacy tag.
 This patch replaces the link with that of a fork that's packaged in Debian.
