Fix wrong bool handling of LOG_SHIP_HOURLY

[FxKu]

Setting LOG_SHIP_HOURLY to bool leads to the following error:

2024-10-08 14:52:53,562 - bootstrapping - INFO - Writing to file /run/etc/log.d/env/LOG_SHIP_HOURLY
Traceback (most recent call last):
  File "/scripts/configure_spilo.py", line 1198, in <module>
    main()
  File "/scripts/configure_spilo.py", line 1160, in main
    write_log_environment(placeholders)
  File "/scripts/configure_spilo.py", line 806, in write_log_environment
    write_file(log_env[var], os.path.join(log_env['LOG_ENV_DIR'], var), True)
  File "/scripts/spilo_commons.py", line 76, in write_file
    f.write(config)
TypeError: write() argument must be str, not bool

Not sure, why tests do not catch this, because in my test the cluster does not even start.
