libavutil: Make LOCAL_ALIGNED(xx be equal to LOCAL_ALIGNED_xx(

Browse Source 
Previously, the former form always produced a manually aligned,
padded buffer, while the latter can use DECLARE_ALIGNED, if that
amount of stack alignment is supported.

libavutil/internal.h needs to include mem.h, since it uses
the DECLARE_ALIGNED macro.
