mount-passthrough: Ignore signals sent during shutdown

Replace fuse_main() with equivalent function calls.

Before this CL:
 fuse_main() installs its own signal handlers, but replaces them with
 the default signal handlers during shutdown.
 This results in unclean shutdown when getting multiple signals.

After this CL:
 Signals sent during shutdown are ignored.

BUG=b:183343552
TEST=No error in /var/log/upstart.log after `for i in $(seq 100);do stop arc-removable-media;start arc-removable-media;sleep 0.5;done`
