  [llvm-exegesis] Add error handling for fork failures (#65186)

There are still some transient failures on the clang-avx512 builder on
the new subprocess memory tests. Some of them seem to be related to an
inability to fork, but it's hard to debug currently as there is no
explicit error handling for a failed fork call, and nice error reporting
for a failed fork is something that we should have regardless.
