V8: increase number of shards for arm64 gc stress.

V8: increase number of shards for arm64 gc stress.

Reason: shard#0 is timing out on swarming.
Expected follow up: if this helps, shard in other 
builders as well.

Not sure if more shards are desirable here. The problem at hand is very few,
extremely long running tests:
https://build.chromium.org/p/client.v8.ports/builders/V8%20Linux%20-%20arm64%...

With more shards, the long running tests would still creep around in a
particular shard and make it time out, as e.g. happened here:
https://build.chromium.org/p/client.v8.ports/builders/V8%20Linux%20-%20arm64%...

The right solution is to speed up or skip the test introduced here:
https://codereview.chromium.org/2224253003

bmeurer, friendly ping...

A revert of this CL (patchset #1 id:1) has been created in
https://codereview.chromium.org/2291703003/ by machenbach@chromium.org.

The reason for reverting is: The root cause of the slow tests has been fixed. A
shard increase is not needed..
