sudo -U <user> -l as root does not display some entries correctly

[aayla-secura]

An entry like the following:

test ALL = () /bin/ls

would allow user test to run both ls as themselves (the invoking user). When sudo -l is invoked by user test this is shown correctly. But when root runs sudo -U test -l, the output implies user test can run ls as root:

# sudo -U test -l
User test may run the following commands on ip-172-31-28-2:
    (root) /bin/ls

This is fixed by 6a0f7cc

# sudo -U test -l

User test may run the following commands on xerxes:
    (test) /bin/ls
