Tao Bao 2be9737cf4 Remove the FD parameter from FuseDataProvider ctor.
This leaves the FD implementation details to subclasses. In particular,
it allows minadbd to do additional works with the FD after sideloading.

Bug: 128415917
Test: atest recovery_component_test
Test: atest minadbd_test
Test: Sideload package on taimen.
