Reverse the junction/link to "ssl" dir

Now the certs are stored under "<ruby>/lib/..." and "<ruby>/ssl" is linked to this directory per innosetup installer.

Before this commit, the link was the other way around, but junctions can not be stored/restored in a 7z archive.
This led to certs not found when 7z archive was used, like in ruby/setup-ruby.

Fixes #405

 Instead add certificates as described below.
 
+Location of the bundled certificates
+------------------------------------
+The storage directory of the bundled certificates varies depending on the ruby version.
+Due to a junction created by the installer the certs can always be found in `<install-path>/ssl`.
+When using the 7z archive the link is not present, but the certificates are stored here:
