Include missing newline in 'man' error

Browse Source 
Because the `strerror` result doesn't include a newline, we need to add
one.  Observed on a minimal system that doesn't have `man` installed,
which behaves like this before the fix:

```
[root@upper tim]# zpool help import
couldn't run man program: No such file or directory[root@upper tim]#
```
