[fix] prevent multiple, parallel initializations of tables in the cache DB (#4991)
Depending on the respective runtime behavior, it could happen that the initial
loading of the DB tables in the cache was performed multiple times and in
parallel. The concurrent accesses then led to the `sqlite3.OperationalError:
database is locked` exception as in #4951.

Since this problem depends significantly on the runtimes (e.g., how long it
takes to retrieve the content for a table), this error could not be observed in
all installations.

Closes: https://github.com/searxng/searxng/issues/4951
