ltp-testsuite: disable tirpc tests using authdes_create

In buildroot, libtirpc is patched to remove authdes_create functions.
As a result, compilation of tests that use these functions, fails.

A previous fix was implemented in commit
8f1c4c49a2ab0fc9e6cf73370f4483e253e5ac2d, but simply disabled linking with
libtirpc entirely. This broke usage of ltp-testsuite on targets where the
toolchain does not have RPC support and libtirpc is mandatory.

Instead, disable only the problematic tests, leaving ltp-testsuite usable
with libtirpc.

+rpc-tirpc: disable tirpc_auth_authdes_seccreate tests
+
+Due to Buildroot patch 0007-Disable-DES-authentification-support.patch on
+libtirpc, this library is built without method authdes_create. Any code
+that uses this library, like the rpc-tirpc testsuite, thus fails to link.
+
+In the context of Buildroot, instead of disabling ltp-testsuite entirely,
+just disable the problematic tests.
