rust: Suppress default sysroot unconditionally
With proper prebuilt modules, we can avoid any rustc implicit sysroot searching. Asd a bonus, this should make rust-project.json generation correctly grab otherwise implicit dependencies. Prebuilt rlibs may include several dependency rlibs. Without a link_dirs attribute, every dependency (even if unexported) would need a separate module. Previously we were casing out on exact structs, which might be OK when libraryDecorator and procMacroDecorator were the only possibilities, but repeating the logic for three types is too much. Using an interface makes this logic scale better. Bug: 159591910 Test: cd external/rust; mma; m crosvm.experimental Change-Id: Ia1124e09f48cd05e39f094bbcb988622ebd2272f
