kunit/usercopy: Disable u64 test on 32-bit SPARC

Browse Source 
[ Upstream commit 0d6efa20e3 ]

usercopy of 64 bit values does not work on 32-bit SPARC:

    # usercopy_test_valid: EXPECTATION FAILED at lib/tests/usercopy_kunit.c:209
    Expected val_u64 == 0x5a5b5c5d6a6b6c6d, but
        val_u64 == 1515936861 (0x5a5b5c5d)
        0x5a5b5c5d6a6b6c6d == 6510899242581322861 (0x5a5b5c5d6a6b6c6d)

Disable the test.
