Add dependency on unsound platform files.
This should fix the following flaky CQ failure:
FAILED: dev_compiler/build/web/dart_stack_trace_mapper.js
Error: Input file not found: dart2js_platform_unsound.dill.
...
Compilation action tries to read the unsound version of the platform,
but the GN template only specifies the dependency on the sound platform
making build non-hermetic.
