Kunhui-Li 93ea0075dd config_tools: update the regex pattern of offline cpu 
The pattern matching logic (used by 'tr') is erroneous in the launch
script generation logic. While its purpose is to return the CPU number
from the 'cpuX' string (where 'X' is the CPU number),
it does it incorrectly for any multiple of 10. Examples:
- Processing 'cpu10' returns 1 (instead of 10)
- Processing 'cpu20' returns 2 (instead of 20)
This patch changes the [1-99] pattern matching to [0-9] which fixes it.

This error led to the incorrect CPU cores being used (and offlined)
for some VMs which could lead to confusing problems especially when
an exclusive use of that CPU core was assumed and expected (e.g. RTVM).

when CONFIG_BOOTPARAM_HOTPLUG_CPU0 is turned on in the kernel,
there is a risk that we try to offline cpu0. So we also add extra check
for cpu0 to aviod the risk.
