[cr133] Fix Linux installer appdata exclusion

For the Linux installer, Brave replaces the existing chromium files with
its own under `chromium_src/`, however these files were renamed
recently, which has broken the exclusion of the upstream files.

    [Linux Packaging] Unify Chromium and Chrome appdata template

    Also there's only one file in the following directories:
    * chrome/installer/linux/common/chromium-browser
    * chrome/installer/linux/common/google-chrome
    So move the files out of the directories and into
    chrome/installer/linux/common.
