[PATCH] uml: fix compilation for missing headers

Re-add some needed headers inclusion deleted in
http://linux.bkbits.net:8080/linux-2.5/cset@41e49628dGbOWX-bT9yZII4f19GT6A

If you think it cannot make sense to include both <sys/ptrace.h> and
<linux/ptrace.h> (as userspace process, i.e.  host includes), go complaining
with glibc, or follow the linux-abi includes idea.

However, the compilation failure is possibly glibc-version (or better glibc
includes version) related - what I now is that the failure happens on my
system with a glibc 2.3.4 (from Gentoo).

Also, fix the syscall table to both compile and have no empty slot (which
could cause Oopses).
