cbfstool: make endian detection code more robust
Accessing the memory of a char array through a uint32_t pointer breaks
strict-aliasing rules as it dereferences memory with lower alignment
requirements than the type of the pointer requires. It's no problem on
x86 as the architecture is able to handle unaligned memory access but
other architectures are not.
Fix this by doing the test the other way around -- accessing the first
byte of a uint32_t variable though a uint8_t pointer.
