signal-desktop: Fix the database encryption by preloading SQLCipher
AFAIK this is the only reliable way for us to ensure SQLCipher will be
loaded instead of SQLite. It feels like a hack/workaround but according
to the SQLCipher developers [0] "this issue can and should be handled
downstream at the application level: 1. While it may feel like a
workaround, using LD_PRELOAD is a legitimate approach here because it
will substitute the system SQLite with SQLCipher which is the intended
usage model;".

This fixes #108772 for NixOS 20.09 users who upgrade to NixOS 21.05 and
replaces #117555.

For nixos-unstable users this will unfortunately break everything again
so we should add a script to ease the transition (in a separate commit
so that we can revert it for NixOS 21.05).
