Enable seccomp in init with generated policy
Test: Ran script to test performance - https://b.corp.google.com/issues/32313202#comment3
Saw no significant regression with this change on or off
Removed chroot from SYSCALLS.TXT - chroot blocked
Boot time appears reasonable
Device boots with no SECCOMP blockings
Measured per syscall time of 100ns
Empirically counted <100,000 syscalls a second under heavy load
