namespace: ensure clone_flags are always stored in an unsigned long
While working on unshare support for the network namespace I noticed we were putting clone flags in an int. Which is weird because the syscall uses unsigned long and we at least need an unsigned to properly hold all of the unshare flags. So to make the code consistent, this patch updates the code to use unsigned long instead of int for the clone flags in those places where we get it wrong today. Signed-off-by: Eric W.
