Porting fixes to #2743 and #2783 to 0.38

[iwankgb]

For details see:

• Cannot read number of sockets correctly, number of sockets set to 0 (ARM64) #2743
• cAdvisor ignores multiple sockets when calculating unique CPU properties #2783
• OOM parsing incorrectly on 5.0 kernels and higher #2813

It will allow us to get kubernetes/kubernetes#95039 fixed.
