[PATCH] uml: support AES i586 crypto driver

We want to make possible, for the user, to enable the i586 AES implementation.
This requires a restructure.

- Add a CONFIG_UML_X86 to notify that we are building a UML for i386.

- Rename CONFIG_64_BIT to CONFIG_64BIT as is used for all other archs

- Tell crypto/Kconfig that UML_X86 is as good as X86

- Tell it that it must exclude not X86_64 but 64BIT, which will give the
  same results.

- Tell kbuild to descend down into arch/i386/crypto/ to build what's needed.
