sysutils/usb_modeswitch: update from 2.2.5 to 2.3.0 and add LICENSE_FILE

Version 2.3.0

• ATTENTION: -I flag is now history and being ignored - determining SCSI attributes is really an 'outside task'
• -n flag (NeedResponse) is being ignored, CSW response will now always be read
• introduction of parameter "OptionMode", wrapping the standard bulk message for all newer Huawei devices
• fixed missing variable initialization in dispatcher script which could lead to crash (thanks, Dmitry Kunilov!)
• fixed bug which prevented early logging
• fixed success report for Cisco AM10
• some source code formatting and clean-up

Version 2.2.6

• Renamed function abort(), avoiding possible conflicts in static builds with libjim (thanks, Gustavo Zacharias)
• removed storage class check of interface 0 from dispatcher, enabling new multi-config devices in data package 20151101
