nethack: fix SYSCF_FILE location
https://github.com/void-linux/void-packages/pull/27036

Description:
I wasn't able to enter the wizard mode, not even as root, e.g. `sudo nethack -D -u wizard` just printed 
```
Entering explore/discovery mode instead
```
Then I found out that `SYSCF_FILE` in the template was pointing to the directory `/usr/lib/nethack` instead of the file itself `/usr/lib/nethack/sysconf`, and used `gdb` to verify that this had lead to `src/files.c:parse_conf_file` silently failing (parsing nothing) and `sysopt.wizards` ending up empty. Updating the `SYSCF_FILE` value fixed the issue, and now the sysconf file is read and I'm able to access the wizard mode.
