tests/shell: return 77/skip for tests that fail to create dummy device

There are some existing tests, that skip operation when they fail to
create a dummy interface. Use the new exit code 77 to indicate
"SKIPPED".

I wonder why creating a dummy device would ever fail and why we don't
just fail the test altogether in that case. But the patch does not
change that.
