[PATCH 2/3] setup: fix safe.directory key not being checked

["Matheus Valadares via GitGitGadget" <gitgitgadget@gmail.com>]

From: Matheus Valadares <me@m28.io>

It seems that nothing is ever checking to make sure the safe directories
in the configs actually have the key safe.directory, so some unrelated
config that has a value with a certain directory would also make it a
safe directory.
