binfmt_flat: Remove shared library support
In a recent discussion[1] it was reported that the binfmt_flat library
support was only ever used on m68k and even on m68k has not been used
in a very long time.
The structure of binfmt_flat is different from all of the other binfmt
implementations because of this shared library support and it made
life and code review more effort when I refactored the code in fs/exec.c.
Since in practice the code is dead remove the binfmt_flat shared library
support and make maintenance of the code easier.
