storage: renumber lookup tests

The next patch will be adding tests, including adding a parameter
for testing more conditions.  For ease of review of that patch, I
want to create common context lines that don't change when the new
tests are added (it's easier to visually review additions than it
is to review an entire chunk of tests rewritten into another
larger chunk of tests).

* tests/virstoragetest.c (mymain): Add a parameter and renumber
the lookup tests.
