[LTP] [PATCH] syscalls/keyctl06: Print TFAIL if keyring_read() returns wrong size

[Xiao Yang]

According to keyctl06's message, the mentioned bug is introduced
by the following patch which is merged into kernel since v3.13:
'b2a4df200d57 ("KEYS: Expand the capacity of a keyring")'

However, we still got the following output before v3.13:
 tst_test.c:958: INFO: Timeout per run is 0h 05m 00s
 keyctl06.c:60: BROK: KEYCTL_READ returned 8 but expected 4

In old kernels, the output exposed that keyring_read() could not
return the size of data read into buffer, because it just returned
the size of a keyring.  So i think this issue should be targeted
as TFAIL.
