tracing: Update funcgraph-retval documentation
The existing documentation for funcgraph-retval is outdated and partially
incorrect, as it describes limitations that have now been resolved.
Recent changes (e.g., using BTF to obtain function return types) have
addressed key issues:
1. Return values are now printed only for non-void functions.
2. Values are trimmed to the correct width of the return type, avoiding
garbage data from high bits.
