Subject: [PATCH 1/3] jenkins/kola/packet.sh: Remove hardcoded arm64 parallel
 test limit

The arm64 tests on EM sometimes hit the timeout.
Remove the hardcoded limit of 3 tests to default to 4 and otherwise
use the overwritten parameter.

Subject: [PATCH 2/3] jenkins/kola/azure.sh: Align the timeout with the GC
 duration

The kola test run time shouldn't be longer than the GC duration to
prevent failing tests caused by GC interference.
Align the Azure kola timeout with the GC duration.
