Petr, please correct me if I'm wrong.  Changing an existing LTP test so
that it only works on kernels with the kernel patch applied, doesn't
sound right.  The test should emit a warning if the original "valid
payload" successfully loads.

As previously suggested, instead of replacing the existing valid
payload, define a new valid payload as the hex-ascii representation of
the existing one.  The kernel decrypted data would then be the same on
systems with and without the patch.

 #define ENCRYPTED_KEY_VALID_PAYLOAD    "new enc32 user:masterkey 32 abcdefABCDE
F1234567890aaaaaaaaaa"
+#define ENCRYPTED_KEY_VALID_PAYLOAD_NEW   "new enc32 user:masterkey 32 b61626364656
64142434445463132333435363738393061616161616161616161"
