The GFNI routines in the AVX version of the ARIA implementation now use
explicit VMOVDQA instructions to load the constant input vectors, which
means they must be 16 byte aligned. So ensure that this is the case, by
dropping the section split and the incorrect .align 8 directive, and
emitting the constants into the 16-byte aligned section instead.

Note that the AVX2 version of this code deviates from this pattern, and
does not require a similar fix, given that it loads these contants as
8-byte memory operands, for which AVX2 permits any alignment.
