tools/gdb: fix thread command not working

Browse source 
`thread` is a GDB prefix command. Use `define` can only change it to a
user prefix command. In this case, `thread 3` is unable to pass
the argument 3 to python.

Use python code to register command to overwrite this behavior. It may
not work with future GDB, but all is good for now.
