rust: Rust sanitized snapshots variations
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
