fix(navigation): workaround dired+ incompatibility with dired in master branch

Commit 194d54a929a83fede75d618b104acd1b544feb10 changed behavior of
deletion functions in Dired, causing Dired+ to break deletion, as it
wholesale replaces a bunch of Dired functions with it's own
implementation. For now I've just copied the Dired variants of those
functions to restore them.
