BUG: refguide-check: respect the verbosity

[ev-br]

Consider

$ python runtests.py -s numpy.lib.recfunctions --refguide-check -v

Previously, the -v switch was silently ignored.

With this PR, the output is

$ python runtests.py -s numpy.lib.recfunctions --refguide-check -v

           (10, (11., 12), [13., 14.]), (15, (16., 17), [18., 19.])],
          dtype=[('a', '<i4'), ('b', [('f0', '<f4'), ('f1', '<u2')]), ('c', '<f4', (2,))])
ok

which might be a tad too noisy for some tastes. I'd suggest to treat this as a bugfix and consider various levels of verbosity between above and the default dots ..... as a separate enhancement.
