NetworkManager insists that plugins be root-owned.  This is the case when running
guix-daemon with root privileged, but not when running it unprivileged (in that case,
file in the store belong to the 'guix-daemon' user.)

Skip that test entirely since it doesn't provide any additional safety on Guix System.

See <https://issues.guix.gnu.org/78047>.
