Fixed posix group checkbox.

In the adder dialog for groups the checkbox has been modified to use
the correct field name "nonposix" and be checked by default.

Note: This is a temporary fix to minimize the changes due to release
schedule. Eventually the field label will be changed into "Non-POSIX
group" and the checkbox will be unchecked by default, which is more
consistent with CLI.
