Fix GCC 8.3.0 warning: ‘packed’ attribute ignored.

Fix the following GCC 8.3.0 warning:

aom/aom_dsp/simd/v64_intrinsics_arm.h: In function ‘u32_store_unaligned’:
aom/aom_dsp/simd/v64_intrinsics_arm.h:74:3: error: ‘packed’ attribute ignored for type ‘uint32_t *’ {aka ‘unsigned int *’} [-Werror=attributes]
   *((__attribute((packed)) uint32_t *)p) = a;
   ^

GCC 8.3.0 ignores __attribute__((packed)) on individual variables, but
we can tell it that a struct is packed (unaligned), which has the same
effect.

Note: Our Jenkins nightly builds use GCC 6.3.0, which does not emit this
warning.
