Show entire path for checkpointing

[Eirik Nygaard <eirikn@xxxxxxxxxxxx>]

When a program is being checkpointed the checkpoint file is stored in the cwd
for the program in question, which might be anything. So I have a patch here
that instead of just showing the filename of the new checkpoint file, it also
shows the path where it is stored.

This patch depends on another patch I have here which separate the __getcwd
function into a syscall part and a kernel part.

Any feedback would be great.
