Pull more KUnit updates from Shuah Khan:
 "Features and fixes:

   - simplify resource use

   - make kunit_malloc() and kunit_free() allocations and frees
     consistent. kunit_free() frees only the memory allocated by
     kunit_malloc()

   - stop downloading risc-v opensbi binaries using wget

   - other fixes and improvements to tool and KUnit framework"
