This adds support for correctly handling Rust sanitized snapshots, ensuring they only have one variation. The presence of multiple variations were causing build failures when a rust_fuzz module for host was defined and a snapshot build was requested. This also sets -Z link-native-libraries=no on host modules (in addition to device modules) to avoid emitting extra linkage flags due to link attributes. Bug: 282897366 Test: SOONG_SDK_SNAPSHOT_USE_SRCJAR=true m Change-Id: Idf980c29145f11c530ad635a4eb5b01a1730ac24
