Load fonts directly from Gerrit instead of 3rd party domains
In environments without public Internet access or where tight control
of loaded resources is necessary, loading fonts from 3rd party domains
might be restricted. Hence, we switch to the fonts directly supplied
by Gerrit.
gitiles loads only the fonts 'Open Sans' and 'Source Code Pro'. Gerrit
provides 'Open Sans' directly and offers 'Roboto Mono' as monospace
alternative to 'Source Code Pro'.
