8a7d0d1cb3 Use a nested userns&mntns to pre-pivot_root
This addresses a latency issue - chroot_fs_refs called inside pivot_root
in the kernel can take several milliseconds on machines with many threads
running.
This might not always reduce latency for custom forkservers, as additional
fork can be more costly than pivot_root.

78824353d1 Make PolicyBuilder a value class.
This makes the class more ergonomic because
* You don't have to heap allocate the builder.
* You can create a policy builder "template" and re-use it across sandboxes to avoid repetitive work.

c6b8e301e4 This fixes broken _proto_cc_cc_proto build target suffixes.
These where inadvertently introduced in an internal cleanup change.

This change also removes a C++17-ism in var_proto.h. To make things easier for
downstream projects, we should stick to C++11 for the time being.
