openjpeg: Don't build with SSE instrinsics for 32-bit x86.
Fixes 32-bit clang-cl build.
These intrinsics require addresses with 16-byte alignment, which doesn't
cause issues for 64-bit builds because of allocator alignment. MSVC
doesn't recognise the __SSE__, __SSE2__ defines, which is why this problem
never surfaced before.
