CtsSettingsHostTestCases secondary_user

Marks this CTS test module as NOT supporting secondary_user, meaning that
the tests should not be run from a user other than the system user.

Module, at least right now, only tests features related to device owner.
Device ownership can only be established from the system user.

Note that 'user' here refers to the concept of users in Android
Multiuser; it is NOT the same as a uid.

Bug: 141773058
Test: module passed with secondary_user params
 (--enable-optional-parameterization --module-parameter secondary_user)
