Revert 79867 - Revert 79618 - Landing for Julien Tinnes, jln@google.com:

chroot to /proc instead of /tmp. This gets rid of a lot of unnecessary
complexity and fixes a race condition.
(Original idea from Markus)
The chroot helper will chroot to /proc/self/fdinfo (or /proc/self/fd). This is
pretty safe because access to this directory is protected by the ptrace() check
in the kernel and the helper is privileged.
Moreover, as soon as the helper _exit() and becomes a zombie, the directory
will be empty. Zygote should wait() for us to make everything deterministric.
We also export SBX_HELPER_PID so that Zygote can specifically wait for the
helper.
