forkserver: Remove order dependent tests
...
Sending -1 as fd will fail and take forkserver down.
This should not happen normally so turned it into a check.

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.
