fuzz: Remove enumeration of expected deserialization exceptions in ProcessMessage(...) fuzzer
Summary:
The exceptions thrown by the libstdc++ and libc++ standard libraries seems to differ for iostream errors. libstdc++ will output iostream error while libc++ will output unspecified iostream_category error. This means that the expected serialization messages [...] don't always work.
Backport of core PR18757.
Test Plan:
