liblo : bump version to 0.29

Starting from version 0.28, C++ wrappers are provided as well. The
configure script appropriately detects the availability of a C++
compiler so no Buildroot changes are needed for this.

Building fails with --enable-ipv6 so --disable-ipv6 is needed in
CONF_OPTS.  This is known by liblo developers and building without
ipv6 support is recomennded.

Included hash for license files.
