check_users: Use sd_get_uids instead of sd_get_session

Previously check_users in combination with systemd used
sd_get_sessions (3) to aquire the number of users, probably
with the idea that every users opens a session.
Turns out, that a user can have multiple sessions and we only really
want to know how many users there are.

This commit changes to sd_get_uids (3) to achieve that target.
