dashboard: switch host-freebsd-13_0-big to e2-standard-4 machines
This reduces the freebsd-amd64-race builder to 4 vCPUs instead of 16,
which should also reduce the default GOMAXPROCS and default
-test.parallel settings on that builder.
The theory is that by switching to a standard CPU-to-RAM ratio, we
will avoid OOMing in memory-bound x/tools tests, which scale their
parallelism by GOMAXPROCS rather than the machine's total RAM size.
For golang/go#49347
