More robust way of echoing $PATH

When we start a login shell to find the natural value of $PATH, instead
of executing `env` in that shell then grepping for $PATH, we simply
`printf` the $PATH directly.

This should be more robust (by virtue printing the value directly rather
than indirectly with env and then using a grep search for the answer.)
