[PATCH v9 2/5] oe-selftest/cases/wic.py: update WicTestCase

[Trevor Woerner <twoerner@gmail.com>]

The wic oe-selftest defines its own class (WicTestCase) for handling
setup, teardown, and various other pieces needed to run the individual
wic oe-selftests. As part of oe-core, the wic.CLITests do not need
setup and teardown. However, once wic is no longer part of oe-core, the
oe-selftests will need to know where to find wic that comes from a
recipe. Update PATH so wic will be available.

NOTE: this patch is in preparation for removing wic from oe-core
      the wic oe-selftests work fine with this patch being added now
