Subject: [PATCH] Enforce exec should find sysctl, test from path

On Gentoo, sysctl is in `/usr/sbin`, not `/sbin`, resulting in an error
like:

```
Error: Could not find command '/sbin/sysctl'
Error: /Stage[main]/Sysctl[vm.min_free_kbytes]/Exec[enforce-sysctl-value-vm.min_free_kbytes]/returns: change from notrun
```

Other `exec`s in this defined type use the path to find `sysctl`, so
the enforce `exec` should as well.
