v2.2.2 - stable

fix

• Fix some bugs that caused the beacon to fail to start when loading the custom communication protocol library.

New

• Add two mandatory beacon running methods for loading custom communication protocol library

1. export CCPATH=/opt/ && /tmp/c2

2. /tmp/c2 /tmp/c2-rebind.so
   (Mandatory loading of communication protocol library for beacon)
