rust: Use v0 mangling format globally

By default, rust uses the `legacy` mangling format. Using llvm coverage
switches it to using the new `v0` format. Rather than pushing the llvm
coverage back to `legacy` format, move Android forwards to `v0`. This
also has the added benefit that Rust symbols can be detected in the
codebase by looking for a leading "_R", aiding in demangler selection.

Test: builds, resulting object files have leading _R rather than _Z
Test: atest keystore2_test
