{J,CS}SResourceLocator: account for symlinks in app path 

Currently, if the app path includes a symlink, the calculated webDir
will be incorrect when generating CSS and URLs will be pointing to the
wrong place, breaking CSS.

Use realpath when retrieving app path, and these issues go away.

Fix #6028
