Sets the UNIX file descriptors associated with message. As a
side-effect the gio.types.DBusMessageHeaderField.NumUnixFds header
field is set to the number of fds in fd_list (or cleared if
fd_list is null).
This method is only available on UNIX.
When designing D-Bus APIs that are intended to be interoperable,
please note that non-GDBus implementations of D-Bus can usually only
access file descriptors if they are referenced by a value of type
G_VARIANT_TYPE_HANDLE in the body of the message.
