Please consider unblocking Chromium and linux packages for Buster

[Lazar Tadić <lazar.tadic34@gmail.com>]

Chromium is currently 2 major and 3 minor versions behind upstream in
both Stretch and Buster. Please consider uploading a recent version to
address 34 open security issues, before the complete freeze on 25th of
June.

Likewise, linux package in Buster lack recent fixes for SACKs
Panic vulnerabilities. I hope it will also be uploaded soon.

Regards,
Lazar
