cfg: In develop mode, use /var/lib for DB and sessions

- Only effects develop mode.

- To primarily avoid writing to the source code directory. Multiple containers
or VMs using the source folder won't fight with the database file (the overlay
file system plan is not working out well for containers #1873).

- In the earlier days, we used to allow running from source code directory
without even doing ./setup.py install. Currently it is not possible anyway. We
pretty much install freedombox package before running from source directory.

- If the build process itself learns not to write to source directory, then
containers/VMs won't have to write to source directory at all.
