create sqlite database file if it does not exist

[fho]

When a volume mount is used for /var/wwww/wallabag/data, as documented^1, the container fails to start with the error messages:

wc: /var/www/wallabag/data/db/wallabag.sqlite: No such file or directory
Configuring the SQLite database ...
In ExceptionConverter.php line 76:
  An exception occurred in the driver: SQLSTATE[HY000] [14] unable to
  open database file
[..]

In the volume mount the db directory and the empty db/wallabag.sqlite do not exist which causes the issue.

Check in the entrypoint script if the file exist, if it does not create the db directory and the file and make nobody the owner.
