julia: remove wrapper from julia binaries, in stead

symlink shared libraries from LD_LIBRARY_PATH into lib/julia,
as using a wrapper with LD_LIBRARY_PATH causes segmentation
faults when program returns an error:

 $ julia -e 'throw(Error())'

only applied for 0.6, which is the current julia version. Will
see if we can remove the older versions in master.
