batctl: Add openwrt revision to internal version

OpenWrt is using a modified version of the software and these modifications
may introduce extra bugs (or behavior changes). It is also patched for
stable releases instead of switching to new releases. The revision should
therefore be added to the version number to make it easier understandable
which modified version the user may have installed.
