    gdb, btrace: simplify gdb.btrace/multi-inferior.exp
    
    We don't really need three inferiors to test multi-inferior recording.
    We don't really need to check info record before starting recording.
    If we were recording, there would be output, causing a fail.
    
    This just complicates the test when there is something to debug.
