Richard Weinberger 0750e8b865 um: Fix PTRACE_POKEUSER on x86_64 ...

commit 9abc74a22d85ab29cef9896a2582a530da7e79bf upstream.

This is broken since ever but sadly nobody noticed.
Recent versions of GDB set DR_CONTROL unconditionally and
UML dies due to a heap corruption. It turns out that
the PTRACE_POKEUSER was copy&pasted from i386 and assumes
that addresses are 4 bytes long.

Fix that by using 8 as address size in the calculation.
