libo_git_from_tar.sh: use curl if wget is not found

Hello,

tried libo_git_from_tar.sh on mac os x and failed because of missing 
wget, since we have curl which should do it let's try tp use it.

This has been lightly tested, read: i've verified that the both on linux 
and on mac os x it starts downloading. It is still running on mac os x 
and tomorrow will know if it worked fine. Anyway the patch looks simple 
enough to be correct.

Please review.

thanks,
riccardo
