test: increase allocation so it fails for the test

It used to be impossible to allocate 1e10 bytes but with a v8 update
this allocation can succeed. This results in 2x10GB allocations and
failure to test the failure :-)

Increase allocation to 1e20 bytes, which should fail for some time,
returning the test to using only 50MB at runtime.
