pythongh-111178: Fix getsockaddrarg() undefined behavior (pythonGH-131668)

Don't pass direct references to sockaddr members since their type may
not match PyArg_ParseTuple() types. Instead, use temporary 'int' and
'unsigned char' variables, and update sockaddr members afterwards.

On FreeBSD, treat BTPROTO_HCI node name as a bytes string,
not as an integer.
