Fix strict-aliasing problems in rijndael.c

We used to use -fno-strict-aliasing but only if configured in
maintainer-mode.  Thus with gcc-4.4 we could run into problems.  The
fix is to define a new type with the may_alias attribute and use this
for the casting stuff in do_encrypt_aligned and do_decrypt_aligned.
