Move SystemBus init to early stage

The bmcweb crash issue seen when there is eventservice
config with subscriptions in persistent file.

During EventService instantiation, it uses the "get_io_context()"
from systemBus, so it should be called after systemBus init. So
moved systemBus initialization to early stage of main process to
avoid ordering issue.

Tested:
 - bmcweb crash issue resolved.
