bitmap: introduce BITMAP_FROM_U64()
The macro is the compile-time analogue of bitmap_from_u64() with the same
purpose: convert the 64-bit number to the properly ordered pair of 32-bit
parts, suitable for filling the bitmap in 32-bit BE environment.
Use it to make test_bitmap_parselist() correct for 32-bit BE ABIs.
Tested on BE mips/qemu.
