tests: fix spurious failure when dependency tracking is unavailable

Report by Dave Goodell.  See automake bug#8880.

* tests/yacc-dist-nobuild.test: Run the sanity check that aims at
ensuring we really cover the expected code paths in a new build
directory, to avoid spurious failures when automatic dependency
tracking is disabled.
