Set up a file logger

Get a file path from the `LOG_FILE` environment variable and use it for
log output.

Call `database::get_database_connection()` and log the error if it
fails.

Worried about exiting early from the FastCGI program, as DreamHost says
this causes problems
(https://help.dreamhost.com/hc/en-us/articles/217298967). But I don't
see how the program can continue without a database connection.

Return a `Result` from `main()` because it's easier to use the `?`
operator for errors that happen before logging is initialised.
