[dpdk-dev] [PATCH v3] cpu_layout.py: adjust output format to align

[Shannon Zhao <zhaoshenglong@huawei.com>]

Bug: when "core id" is greater than 9, the cpu_layout.py output doesn't align.

        Socket 0        Socket 1
        ---------       ---------
Core 9  [4, 16]         [10, 22]

Core 10         [5, 17]         [11, 23]

Solution: adjust output format to align based on the maximum length of the "core id" and "processor"

        Socket 0        Socket 1
        --------        --------
Core 9  [4, 16]         [10, 22]

Core 10 [5, 17]         [11, 23]
