systemd/networkmanager: don't build docs (MR 5563)

This doens't work with crossdirect since apparently it calls the

ERROR: ['/usr/bin/gtkdoc-scangobj', .... failed with status 1
============================================================================================
ERROR: crossdirect was called with: LD_PRELOAD=libfakeroot.so
