nr-cuup-load-test: avoid unaligned memory access

Use memcpy() instead of unaligned pointer access

tests/nr-cuup/nr-cuup-load-test.c:431:16: runtime error: store to misaligned address 0x756d02eca1a2 for type 'uint32_t', which requires 4 byte alignment
tests/nr-cuup/nr-cuup-load-test.c:267:14: runtime error: load of misaligned address 0x756d095edcf6 for type 'uint32_t', which requires 4 byte alignment
