ANDROID: Only warn on long symbols

Browse Source 
Rust symbols frequently exceed the maximum length for a MODVERSIONS
symbol. If this happens, warn and continue rather than erroring out.
This is intended to support testing of the Rust binder driver as a GKI
module.

This change is Android-only because we are pursuing a more complete
strategy upstream, but this is suitable for a GKI-module trial of the
Rust binder driver:
