Clean up fuse_sideload and add a testcase.
This CL mainly changes:
a) moving the interface in struct provider_vtab to std::function;
b) code cleanup, such as moving the declaration closer to the uses,
using explicit type conversion.
Test: recovery_component_test
Test: minadbd_test
Test: Sideload a package on marlin.
