This as well forces to move ptrace
definitions into ptrace.h, otherwise
freshly fetched kernel headers become
conflict with existing ptrace constants.

Since we operate with syscalls directly we are
to convert signal's structures between image and
kernel formats, without intermediate glibc layer.
Note this involves chaging sa_entry::flags to u64
(since it's long int value in kernel).

This logic is moved from kernel do_signal().

Tejun Heo proposed to use more general names
unrelated to checkpoint-restore procedure.
So be it (maybe someone else will need this
entries as well).

They are actually banned in kernel for now, but
we might end up needing them, so better to have
them in-place.
