Split bootbios.asm and kernel.asm.

* Move bios-related part of kernel.asm before B32 label to
  bootbios.asm file;
* Move bx_from_load, boot_dev and kernel_restart_bootblock variables
  to BOOT_* 0x9000 block;
* Update Tupfile.lua, Makefile, build.bat, build.sh accordingly;
* Now bios and uefi loaders can jump to very first byte of the kernel.
