CLOUDSTACK-5993: Cloud agent fails to start on 32-bit system vms (cpvm and
ssvm) created with 4GB RAM offering
Capped the max heap size of the JVM at 2600M for 32-bit system VMs. For
64-bit, existing logic works fine.

> While attempting to provision beefier system vms, we discovered this bug.
> The `_run.sh` script in the system vm calculates jvm memory based on 80% of
> the total memory on the system. This is great up until the point 80% of
> memory goes above ~1.9G. The system vm templates are all 32-bit and so
> calculating the size too high will cause the agent jvm to fail to start.
> The fix is pretty simple with a final sanity check:
> if [ $maxmem -gt 1900 ]
> then
> maxmem=1900
> fi
