Bug#971928: fakeroot: Change to use fixed message sizes broke m68k

Hello!

The change in [1] to use fixed-width members in fake_msg broke fakeroot
on m68k as this change altered the offsets in the fakestat struct due to
the additional #pragma pack(4) statements [2]:

> libfakeroot, when sending message: Invalid argument

On m68k, the default alignment is 16 bits, not 32 bits which is why the
change in [1] affected the offsets in the fakestat struct.

So, for m68k, the #pragma pack() statements will need to be guarded.

Thanks,
Adrian
