Use exec_path to re-execute the binary from /proc/self/exe
Fix do_openat() that should not use execfd.

v2:
- don't use execfd as it can't be closed and is usable by the child

Why can't it be closed? I mean, how about O_CLOEXEC?

I tried O_CLOEXEC, but it seems the fd is closed before it is needed by execveat() to re-spawn the 
process, so it exits with an error (something like EBADF)

Thanks,
Laurent
