Deprecation of 'go get' for installing executables

[DevDengChao]

Starting in Go 1.17, installing executables with go get is deprecated. go install may be used instead.

---

There should be some version comparing in

systray/example/icon/make_icon.bat

Lines 18 to 22 in a47cb5b

	:INSTALL
	ECHO Installing 2goarray...
	go get github.com/cratonica/2goarray
	IF ERRORLEVEL 1 GOTO GETFAIL
	GOTO POSTINSTALL

and

systray/example/icon/make_icon.sh

Lines 8 to 15 in a47cb5b

	if [ ! -e "$GOPATH/bin/2goarray" ]; then
	echo "Installing 2goarray..."
	go get github.com/cratonica/2goarray
	if [ $? -ne 0 ]; then
	echo Failure executing go get github.com/cratonica/2goarray
	exit
	fi
	fi

Otherwise users won't be able to invoke the 2goarray bin to generate an icon.
