[LTP] [PATCH 1/1] lib/safe_net: TCONF SAFE_LISTEN() on ENOSYS

[Petr Vorel]

This is needed at least on bind04 on SLES with Common Criteria setup,
which is more strict and thus does not allow md5 usage:

bind04.c:138: TBROK: listen(3, 1) failed: ENOSYS (38)
sctp: failed to load transform for md5: -2
