problem with symlink in lib/dependencies.sh

[lakamsani]

Hi,

I found and fixed a problem with symbolic link in lib/dependencies.sh that was causing cf push app -b [email protected]:theodo/nodejs-oracledb-buildpack.git to fail when trying to npm install oracledb. Here is the commit where I fixed it.

Now cf push app -b [email protected]:lakamsani/nodejs-oracledb-buildpack.git works.

Not sending a PR because I also changed manifest.xml to use just node 8.8.0 (removed all other node versions) and not everyone may want that part. Feel free to grab the symlink fix as I can confirm it fixed the issue with npm install oracledb. Here is the CF/IBM Cloud version I tested with.
