Patch JULIA_LOAD_PATH

[cako]

There is a well known issue in when using JULIA_LOAD_PATH in that if its value does not end with a ":", it does not find the default depot. See this issue.

In this fix, the env.sh file created will look like this:

if [ -n "$JULIA_LOAD_PATH" ]; then
export JULIA_LOAD_PATH=$RSFROOT/lib:${JULIA_LOAD_PATH}:
else
export JULIA_LOAD_PATH=$RSFROOT/lib:
fi

instead of this

if [ -n "$JULIA_LOAD_PATH" ]; then
export JULIA_LOAD_PATH=$RSFROOT/lib:${JULIA_LOAD_PATH}
else
export JULIA_LOAD_PATH=$RSFROOT/lib
fi

and analogous for env.csh.
