Fix for rexec_af

[Mark Kettenis <kettenis at wins dot uva dot nl>]

The following fix is needed to make inet/rexec.c compile on the Hurd.
Since the Hurd uses a 4.4 BSD compatible struct sockaddr which has a
member sa_len, the trick with __libc_sa_len should not be necessary.
Using the macro SA_LEN should take care of this issue transparantly.

	* inet/rexec.c (rexec_af): Use SA_LEN instead of __libc_sa_len.
