Don't remove one directory level from slspath

This breaks the tpldir jinja context variable for the cases where there
is an SLS path in the format `X.X` (e.g. `foo.foo`, `bar.bar`, etc.).

It also conflicts with the stated documentation for this parameter in
`doc/rev/states/vars.rst`, which states that this variable should be the
path to the SLS target. In reality this is passed in via
`context['sls']` and already has the correct path.

If I were to wager a guess, I would say that it's likely that the way
`context['sls']` is formulated has changed at some point since these two
lines were added in 2014, making these two lines unnecessary.
