Put all the system call stuff in a new module, m_syscalls.  This
required moving a lot of stuff around.  I deleted
VG_(set_return_from_syscall_shadow)() and VG_(get_exit_status_shadow)(),
which screwed up the modularity and weren't being used and can be
simulated in other ways with a bit of care.

What are the chances that I've added and moved all the files correctly
in this commit, and not broken the amd64 port?
