Change the sandbox API to require passing in a copy of /proc instead of
/proc/self. This allows "SupportsSeccompSandbox()" to work correctly, even
after it had to "fork()". Otherwise, the old "/proc/self" would point to
the parent process, and some kernels don't allow accessing it from the
child (even though it is still a valid file descriptor; it just stops
working).
