[zorg] Update container-based Linaro slaves

Summary:
Update container-based Linaro slaves to not include machine name
"linaro-armv8-01", since these slaves are now served by docker
containers on several Linaro machines.

Also decrease "jobs" property setting for such builders from 64 to 32.
These builders share 32-core and 64-core machines, and even on 64-core
machine they can get at most 32-thread parallelism.
