[gdb/testsuite] Handle older python in gdb.python/py-send-packet.py

With python 3.4, I run into:
...
Traceback (most recent call last):^M
  File "<string>", line 1, in <module>^M
  File
  "outputs/gdb.python/py-send-packet/py-send-packet.py", line 128, in \
    run_set_global_var_test^M
    res = conn.send_packet(b"X%x,4:\x02\x02\x02\x02" % addr)^M
TypeError: Could not convert Python object: b'X%x,4:\x02\x02\x02\x02'.^M
Error while executing Python code.^M
...
while with python 3.6 this works fine.

Fix this by avoiding the byte literal (with prefix b), and use instead:
...
  bytes(("X%x,4:" % addr).encode('ascii') + bytearray([0x2, 0x2, 0x2, 0x2])).
...
