Changes: https://netatalk.sourceforge.io/3.1/ReleaseNotes3.1.13.html
Netatalk 3.1.11 is the latest stable release. There is also a nasty bug
with netatalk < 3.1.11 (https://sourceforge.net/p/netatalk/bugs/636/)
that prevents using netatalk shares for time machine backups.
This fixes builds after #4419. Thanks to @vbgl for the original commit;
I changed that as I'm not sure whether passing null values to buildInputs is clean.
