Fix the gdb-client test suite for python3

This applies the same fix that was done in r354106 to the lldb-server
test: bitcasting the string to a bytes object before sending it over a
socket. Since the gdb-remote protocol occasionally contains binary data,
and it does not assign any particular encoding to them, this is the
right thing to do here.
