Create ~/.java/current/ symbolic links in /home/tooling/ instead of /…

…home/user/

In order for stow in the UDI's entrypoint to complete successfully,
any files present in /home/user/ (that are not in the .stow-local-ignore)
must not also exist in /home/tooling/, otherwise a conflict would occur.

Since the symbolic link creation from JAVA_HOME_8/11/17 occurs before stow
is executed, the symbolic link must be created from JAVA_HOME_8/11/17 -> /home/tooling/
to prevent a stow conflict.

Stow will then create a symbolic link from
/home/tooling/.java/current/ -> /home/user/.java/current/ so that JAVA_HOME remains valid.
