Incorrect SWIG binding for `semanage_module_install_info`

[Bob131]

There are two issues with the current binding for semanage_module_install_info:

• It takes both a buffer and a length, as separate arguments
• The buffer argument is unmarshalled as though it were a Unicode string and not a binary blob

Running the following code

handle = semanage.semanage_handle_create()
_, info = semanage.semanage_module_info_create(handle)
semanage.semanage_module_install_info(handle, info, b'123', 3)

results in

Traceback (most recent call last):
