ttcn3.sh: set LD_LIBRARY_PATH=/usr/local/lib

Fix for Osmocom programs using system's shared libraries, instead of the
ones mounted into /usr/local.

For example, for osmo-bsc the libosmocore installed in the
osmo-bsc-master docker container would be used (installed via apt from
OBS nightly) instead of the version that osmo-dev built from source.
