[LTP] [V2][PATCH] Fix wrong pattern used by fnmatch in test case proc01.c

[Li Jin]

A single "*" can not be used to match the any string in fnmatch.
Therefore, fnmatch() in proc01.c should use pattern ipv6/conf/?*/stable_secret
to replace /ipv6/conf/*/stable_secret to check the known issue string such as
/proc/sys/net/ipv6/conf/all/stable_secret.

    1. /proc/sys/net/ipv6/conf/[a-z]*/stable_secret -->
