Restructured the include/ directory.

- All the subdirectories have gone: arm/, x86/, amd64/, linux/,         
  x86-linux/, amd64-linux/, arm-linux/.

- The following files were moved out of those directories into include/:

    amd64-linux/vki_arch.h            --> vki-amd64-linux.h
    x86-linux/vki_arch.h              --> vki-x86-linux.h
    x86-linux/vki_arch_posixtypes.h   --> vki_posixtypes-x86-linux.h
    linux/vki.h                       --> vki-linux.h
    amd64-linux/vki_arch_posixtypes.h --> vki_posixtypes-amd64-linux.h

- The following very small files were inlined into tool.h using the "#if
  defined(VGP_x86)..." technique:

    x86/tool_arch.h
    arm/tool_arch.h
    amd64/tool_arch.h

  The same technique was used twice to include the appropriate
  vki-$PLATFORM and vki-$OS files into tool.h.  

- The other files in those directories were removed.

- The build is much simpler, since we have 7(!) fewer Makefile.am files.
  Far fewer -I options are needed when compiling, too.
