[Devel] [PATCH rh7] seccomp, ptrace: Fix typo in filter fetching

[Cyrill Gorcunov]

In commit 42b65fd18057d64410a0519962cd0650c762c99f there
is a typo: we need to copy the complete filter chain
not only first number.

I am continue investigating the problem since tests
are not yet passed but this fix may be applied independently.
