[scudo] Reduce the scope of AllocAfterFork

`ScudoWrappersCppTest.AllocAfterFork` was failing obscurely sometimes.
Someone pointed us to Linux's `vm.max_map_count` that can be
significantly lower on some machines than others. It turned out that
on a machine with that setting set to 65530, some `ENOMEM` errors
would occur with `mmap` & `mprotect` during that specific test.

Reducing the number of times we fork, and the maximum size allocated
during that test makes it pass on those machines.
