SUDO: Only store lowercased attribute value once
The current code doesn't handle the situation where lowercasing the
sudoUser attribute would yield the same value again.
For example:
sudoUser: TUSER
sudoUser tuser
would break.
This patch switches to using the utility function
sysdb_attrs_add_lower_case_string() which already checks for duplicates.
