[compiler-rt] [Fuzzer] Bump max RSS in fork tests (PR #203688)

[Aiden Grossman via llvm-commits]

https://github.com/boomanaiden154 created https://github.com/llvm/llvm-project/pull/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.
