ENABLE_SYSTEMD option has been removed from ubus by upstream commit:
96ab0b3032f5 ubusd: remove systemd socket activation support
From a Buildroot perspective, this means that this systemd socket
activation feature no longer exists since Buildroot commit
130be80d34 ("ubus: bump version"), as we
bumped ubus from 259450f414d8c9ee41896e8e6d6bc57ec00e2b63 to
34c6e818e431cc53478a0f7c7c1eca07d194d692 in this commit, and the
96ab0b3032f5 ("ubusd: remove systemd socket activation support")
commit is in this range. It was therefore dropped upstream in 2016,
and in Buildroot in 2017.
