Explicitly disable FUSE

It is already disabled, but having an explcit value in the prop makes
some code in the system_server, easier.

Will follow up with a cl to explicitly enable it on internal master,
aosp will remain this way since it doesn't have the additional
components to run FUSE.

Test: Freshly wiped and flashed device has persist.sys.fuse set to false
