amend! Bug 41043: Hardcode the UI font on Linux
Bug 43140: Tighten up fonts on Linux.
We ship a fontconfig configuration to esnure all Linux users have the
same defaults and reduce the chances of fingerprinting.
We used to add this file in tor-browser-build, but some users might
skip it by using the browser executable without the wrapper script.
Therefore, we decided to activate the file with the FontConfig API
instead of the environment variables.
Bug 41043: Hardcode the UI font on Linux
The mechanism to choose the UI font does not play well with our
fontconfig configuration. As a result, the final criterion to choose
the font for the UI was its version.
Since we hardcode Arimo as a default sans-serif on preferences, we use
it also for the UI. FontConfig will fall back to some other font for
scripts Arimo does not cover as expected (we tested with Japanese).
Bug 43141: Hardcode system-ui to Arimo.

fixup! Bug 41668: Tweaks to the Base Browser updater for Tor Browser
Bug 41786: Remove the add_if command we added for fontconfig.
We do not need it anymore, as we had the watershed update and, in any
case, we are movign the fonts.conf in tor-browser.git.
