[cpu][linux] Fix #1037 only count logical cores where 2nd field is a number

@blalor can you run go test -v github.com/shirou/gopsutil/cpu on the Android phone you found this issue? This is to check the TestCPUCountsAgainstLscpu test (lscpu should be on the phone, tested on Termux on mine).

If you can't, could you paste the result of LC_ALL=C lscpu as run on the phone?

Thank you for the fix! Unfortunately lscpu is not on the devices I'm working with, which are running Fire OS.

The MT8183 is described as an octa-core chip, and the mocked test finds 8 logical cores.

I feel OK merging that.
