IDcheck: Add check for root user/group

Some tests (e.g. getgid, getegid, etc.) need to have a valid user id and
group for root. Add the check to IDcheck.sh. Also, make a user and a group
for root if necessary.

Merged! Although this might be better handled in the tests or test
library (e.g. add tst_test options for what a test needs in /etc/passwd
and /etc/group).
