papi: Use CMSG_SPACE for sizing ancillary buffer space

CMSG_LEN provides the length required to store an ancillary item, but it
does not consider padding. RFC 3542 requires portable applications to
use CMSG_SPACE(), this is documented in the python API:

https://docs.python.org/3/library/socket.html#socket.CMSG_LEN

Type: improvement
