[LTP] [PATCH v2 2/3] commands/keyctl01: Fix getting key serial number

[Guangwen Feng]

We expect to get the key serial number by matching "debug:fred":

Session Keyring
1072563454 --alswrv      0     0  keyring: _ses
 340758544 --alswrv      0 65534   \_ keyring: _uid.0
 783746283 --alswrv      0     0   \_ user: debug:fred

But in some kernels the key will be inaccessible immediately
after being requested with "debug:fred negate":

Session Keyring
        -3 --alswrv      0     0  keyring: _ses
 842289032 --alswrv      0    -1   \_ keyring: _uid.0
877125164: key inaccessible (Permission denied)

So fix this by adding a match with "inaccessible".
