[PATCH] UnitTestFrameworkPkg: Invalid index may be used.

["GuoMinJ" <newexplorerj@gmail.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2535

The UINT_TEST_STATUS and FAILURE_TYPE have used 0 as status, so use 0 as
unknown is confused, remove it from array enumeration but keep it
location in the array.
