Bumps to v102.1

In #24, we wrongly assumed that ETP Strict Mode was available in TB 102 (as it was for FF 102).

This patch aims to workaround this (security) issue by :

* Re-enabling FPI ;
* Re-enabling DNT header ;
* Restoring `network.cookie.cookieBehavior` tweak ;
* Re-enabling ETP with custom settings (including query parameter stripping) ;
* Re-dealing with persistent storage-related preferences (`2700`).

This increases divergence with Arkenfox upstream template.
