    [gdb/testsuite] Fix gdb.base/trace-commands.exp with editing off
    
    With test-case gdb.base/trace-commands.exp and editing off, I run into fails
    because multi-line commands are issued using gdb_test_sequence, which
    doesn't handle them correctly.
    
    Fix this by using gdb_test instead.
    
    Tested on x86_64-linux.
