make sqlite open errors clearer
Gitea/pysonic/pipeline/head This commit looks good Details
Gitea/pysonic/pipeline/pr-master This commit looks good Details

if filesystem permissions on the directory the sqlite database database file is in are such that the app cannot list or create files, sqlite gives a vague error:

sqlite3.OperationalError: unable to open database file

whereas python's open() will give a better hint ("permission denied"). So, we try opening the database file with python first.

also, add chmods to the startup scripts to avoid this issue in the future
