aes: Enforce alignment of static array
When building on-device unit test binaries, the static array in
test/aes.c were not address-aligned after being linked into the
final binary. This causes "runtest" to emit an exception on device
as the MCU tries to load from the address of the static array which
is unaligned address. Enforce alignment to avoid the error.
