LOG: [Fuzzer] Bump max RSS in fork tests (#203688)

These became flaky on at least one buildbot after enabling the internal
shell by default:
1. https://lab.llvm.org/buildbot/#/builders/174/builds/36874
2. https://lab.llvm.org/buildbot/#/builders/174/builds/36876

Try bumping the max RSS to see if that helps.
