main.cpp in gui_src of cyusb_linux_1.0.5 fails to build on Ubuntu 2020.04, fix suggested

[WaRa_4824346]

Parameter "int errno" on line 74 of main.cpp conflicts with typical C++ usage resulting in compilation errors. 

Changing "errno" to "errnum" and adjusting the remainder of "libusb_error" to use "errnum" fixes the build problem.   After the suggested change, cyusb_linux build and runs.

Modified source code for "libusb_error" is attached.
