BUG: Fix SharedForward in-tree detection
BUG: Fix SharedForward in-tree detection

To detect when the launcher is running from the build tree we now test
if the directory containing it is the same as the build-tree directory
using an inode test instead of string comparison.  This makes it more
robust on case-insensitive filesystems and other quirky situations.
