[PATCH v3 3/3] kunit: Use KUNIT_EXPECT_MEMEQ macro

[Maíra Canal]

Use KUNIT_EXPECT_MEMEQ to compare memory blocks in replacement of the
KUNIT_EXPECT_EQ macro. Therefor, the statement

    KUNIT_EXPECT_EQ(test, memcmp(foo, bar, size), 0);

is replaced by:

    KUNIT_EXPECT_MEMEQ(test, foo, bar, size);

v1 -> v2:
- Change the macro KUNIT_EXPECT_ARREQ to KUNIT_EXPECT_MEMEQ, in order to make
it easier for users to infer the right size unit (Daniel Latypov).

v2 -> v3: No changes.
