not all CPU info is returned

[undertherain]

on less common CPUs, such as Cavium ThunderX2
underlying pycpuinfo, though not reporting brand name, at least shows architecture and number of cores
but this information does not percolate into system_query

sample output of cpuinfo:

$ python3 -m cpuinfo

output of sustem_query:

{'brand': None,
         'cache': {1: 32768, 2: 262144, 3: 33554432},
         'clock': None,
         'clock_max': None,
         'clock_min': None,
         'logical_cores': None,
         'physical_cores': None},

with, say, arch and cores I could have at least rendered this as "Unknown 224 core ARM_8 CPU " or something

@undertherain I think we had a run in with this yesterday!
