update_version.sh: make maven run in batch mode

pongad · pongad · commit 19994a411e8f · 2017-06-09T13:19:55.000+10:00
Newer versions of Maven has colored outputs, which messes with the script.
The -B (batch) option disables colors.

Could folks using older Mavens let me know if your versions accept
the batch option?
