connman: disable version-scripts to fix crashes at startup

With binutils 2.27 on at least MIPS, connmand will crash on startup.  This
appears to be due to the symbol visibilty scripts hiding symbols that stdio
looks up at runtime, resulting in it segfaulting.

This certainly appears to be a bug in binutils 2.27 although the problem has
been known about for some time:

As the version scripts are only used to hide symbols from plugins we can safely
remove the scripts to work around the problem until binutils is fixed.
