avro-c++: Fix build for 32-bit targets

Building avro-c++ for 32-bit targets currently fails due to the following warnings being treated as errors:

- `useless-cast` in Symbol.cc
- `conversion` in FileStream.cc

These are promoted to errors because of `-Werror` in the project's build flags.

Fix:

lib32-avro-c++/1.12/sources/avro-c++-1.12/lang/c++/impl/parsing/Symbol.cc:91:27:
error: useless cast to type 'int' [-Werror=useless-cast]
91 | adj.push_back(static_cast(it - rs.begin()));
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

208 | in_->seek(position - byteCount_ - available_);
| ~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~

lib32-avro-c++/1.12/sources/avro-c++-1.12/lang/c++/impl/FileStream.cc:209:22:
