[LTP] [PATCH] proc/proc01.c: ignore stable_secret files

[Jeffrey Bastian <jbastian@redhat.com>]

Linux 4.1.0 introduced a per-NIC IPv6 stable_secret file for RFC7217.
The stable_secret file for each NIC cannot be read until it is set,
thus LTP fails like this:

proc01      1  TFAIL  :  proc01.c:392: read failed: /proc/sys/net/ipv6/conf/all/stable_secret: errno=EIO(5): Input/output error
proc01      2  TFAIL  :  proc01.c:392: read failed: /proc/sys/net/ipv6/conf/default/stable_secret: errno=EIO(5): Input/output error
proc01      3  TFAIL  :  proc01.c:392: read failed: /proc/sys/net/ipv6/conf/eno1/stable_secret: errno=EIO(5): Input/output error
...

Ignore the stable_secret files in the proc01 test.

TODO: A future test should verify stable_secret functionality.
  ~]# cat /proc/sys/net/ipv6/conf/eno1/stable_secret
  cat: /proc/sys/net/ipv6/conf/eno1/stable_secret: Input/output error
  ~]# echo "ffff:ffff:ffff:ffff:ffff:ffff:255.255.255.255" > /proc/sys/net/ipv6/conf/eno1/stable_secret
  ~]# cat /proc/sys/net/ipv6/conf/eno1/stable_secret
  ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff
