[RFA/testsuite] Fix failures in observer.exp

[Joel Brobecker]

A recent change in the normal_stop observer caused a change in
the profile of observer_notify_normal_stop(). The observer.exp
testcase makes calls to this function, so it should be updated
accordingly.

        * gdb.gdb/observer.exp (test_normal_stop_notifications): Update
        call to observer_notify_normal_stop.

Fixes all the failures during that test. Yah!
Ok to commit?

Thanks,
