[PATCH] add tests for vc-list-files

[Jim Meyering]

I'm slightly leery of adding a test for a non-essential tool like
vc-list-files, since everyone who uses the module will now pull in
this test, and possibly get a test failure.  Such a failure doesn't
really matter in general -- most people don't run "make syntax-check"
or "make distcheck" -- so a test failure here is most definitely no
cause for alarm and no reason not to install the package.

Of course, gnulib-using packages that want to avoid a test like
this can easily just exclude it.

Opinions?
