Remove property-based fused sdcard mounting

Depending on the actions pending on the action queue in 'init', the
2nd stage bind mount can fail due to timeout.  The handling of the
1st stage property trigger to start the service, the setting of the
service running property and the 2nd stage bind mount trigger actions
can sometimes run quickly enough that the fuse sdcard process does not
have time to complete the initial fuse mount before the 2nd stage
bind mount fails due to timeout.

Replace the 2-stage startup trigger logic with always enabled fuse
sdcard service.
