Revert "eos-test-mode: Remount eos-live overlays in some services' na…

…mespace"

This reverts commit 28e58e8.

The underlying bug in ostree was fixed in
endlessm/ostree#214, a backport of
ostreedev/ostree#3292.

With that change, eos-test-mode's overmounted overlayfses propagate
correctly to NetworkManager and AccountsService, so they no longer need
to be restarted. And restarting NetworkManager triggers a bug in Initial
Setup, which does not correctly handle this case and so never lists
available Wi-Fi networks.
