nixos/atop: Fix regression in enabling atop units

Fix regression where the systemd units for atop are no longer
automatically started at boot when programs.atop.enable = true.

Regression was introduced in commit: 09350ff7d4
  nixos/atop: Convert log format to fix service start

This commit restructures the atop systemd service config so that the
code to convert the log format gets configured as a preStart script
along with the addition of the wantedBy rule.
