    [gdb/testsuite] Fix gdb.base/break-dbg.exp without xml support
    
    With a gdb build without xml support and test-case gdb.base/break-dbg.exp, I
    run into:
    ...
    (gdb) catch syscall^M
    warning: Can not parse XML syscalls information; \
      XML support was disabled at compile time.^M
    Catchpoint 11 (any syscall)^M
    (gdb) FAIL: $exp: catch syscall
    ...
    
    Fix this by updating the regexp.
    
    Tested on aarch64-linux.
