fatal: Remote branch 2.4 not found in upstream origin

Hi,

Could not download 2.4 branch with the script.

with
sudo ./build_opencv.sh 2.4

fatal: Remote branch 2.4 not found in upstream origin

I have checked that the 2.4 branch exists.

The problem seems to be that opencv_contrib isn't available for that version. To fix it, please comment out the line:
git clone --branch "$1" https://github.com/opencv/opencv_contrib.git
in the git_source() function (should be around line 44).

I will change the script in the next version so that opencv_contrib will only be cloned if the version is >3.4 (but you are welcome to submit a pull request if you fix it yourself :)
