fix(caldav): write per-calendar khal config instead of broken glob

The glob path = .../calendars/* was not expanded by khal, so no events
were visible. Now caldav-sync.sh and ics-to-calendarim both generate
explicit [[name]]/path entries per calendar and regenerate the config
on every sync so newly discovered calendars are picked up automatically.
