tools: acrn-crashlog: channel module for acrnprobe

Browse Source 
The channel represents a way of detecting the system's events.
So far, there are 3 channels:
1. oneshot, detect once while acrnprobe startup.
2. polling, run a detecting job with fixed time interval.
3. inotify, watch the change of file or dir.
