cffi: pass bytes instead of str to ffi.new("char[]", …)...

cffi: pass bytes instead of str to ffi.new("char[]", …) The type annotations seem to imply that the passed values are always already bytes, but they aren’t necessarily. Before Python 3.11, the documentation stated that bytes can be used to annotate arguments whose type is actually any of bytes, bytearray, or memoryview.
