Wait for hwservicemanager ready before running fsck

As property service is part of init, and if init is busy with built-in
command e.g. fsck, the propety_set() won't go through until the built-in
command is finished.
Move the start of hwservicemanager earlier and wait for its done after
launches bootanim and its dependencies (there is not wait time during
boot but the command is as a safeguard).

Bug: 74437368
Test: boot with simulated long fsck and bootanim shown early
Test: boot see 'start_waiting_for_property("hwservicemanager.ready", "true"): already set'
