useradd-staticids.bbclass: Simplify some logic 

The [<on_true>, <on_false>][not <condition>] construct may solve the
problem of implementing a conditional operator, but it is not very
readable. At least I find this:

    uaargs.groupid = field[3] or uaargs.gid or uaargs.groupname

a lot more readable than this:

    uaargs.groupid = [uaargs.gid, uaargs.groupname][not uaargs.gid]
    uaargs.groupid = [field[3], uaargs.groupid][not field[3]]

Also, the official conditional operator since Python 2.5 (<on_true> if
<condition> else <on_false>) does not evaluate both <on_false> and
<on_true> as [<on_true>, <on_false>][not <condition>] does.
