[PATCH] selftest: wic: split test_debug test case

[Ed Bartosh <ed.bartosh@linux.intel.com>]

Splitted to test_debug_short and test_debug_long to make each
of the test cases to run wic once. This is consistent with the
rest of the test cases and ensures that test cases are set up
properly.

This also fixes the following test failure caused by the image
left from the first wic run:

FAIL: test_debug (oeqa.selftest.wic.Wic)
Test debug
----------------------------------------------------------------------
Traceback (most recent call last):
  File "meta/lib/oeqa/utils/decorators.py", line 109, in wrapped_f
    return func(*args, **kwargs)
  File "meta/lib/oeqa/selftest/wic.py", line 270, in test_debug
    self.assertEqual(1, len(glob(self.resultdir + "directdisk-*.direct")))
AssertionError: 1 != 2
