internal/trace/v2: halve the memory footprint of the gc-stress test
An out-of-memory error in this test has been observed on 32-bit
platforms, so halve the memory footprint of the test. Also halve the
size of steady-state allocation rate in bytes. The end result should be
approximately the same GC CPU load but at half the memory usage.
