selftests/ipc: skip msgque test when MSG_COPY is unsupported
msgque kselftest uses msgrcv(..., MSG_COPY) to copy messages. When the
kernel is built without CONFIG_CHECKPOINT_RESTORE, prepare_copy() is
stubbed out and msgrcv() returns -ENOSYS. The test currently reports this
as a failure even though it is simply a missing feature/configuration.
Skip the test when msgrcv() fails with ENOSYS.
