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

Hi

Hi,

When I run test case proc01 with 4.1 linux kernel, found that fnmatch use a
wrong pattern to match the known issue under /proc/sys/net/ipv6/conf/ such as
/proc/sys/net/ipv6/conf/all/stable_secret, and have the following error:

[root@localhost tmp]# ./proc01 
proc01      0  TINFO  :  /proc/sys/fs/binfmt_misc/register: is write-only.
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/bond0/stable_secret: errno=EIO(5): Input/output error
proc01      3  TFAIL  :  proc01.c:392: read failed: /proc/sys/net/ipv6/conf/default/stable_secret: errno=EIO(5): Input/output error
proc01      4  TFAIL  :  proc01.c:392: read failed: /proc/sys/net/ipv6/conf/eth0/stable_secret: errno=EIO(5): Input/output error

Test passed with the following change

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

[root@localhost ~]# ./proc01
