Bram Bonné acadd09c66 Speed up seccomp with priority list. 
Allow to provide a list of prioritized syscalls (e.g., syscalls that we
know occur often) which are checked before other syscalls in seccomp.

When constructing the bpf seccomp filter, traverse prioritized syscalls
in a linear list before checking all other syscalls in a binary tree.

Bug: 156732794
Test: make, inspect generated *_system_policy.cpp files
Test: simpleperf on futex/ioctl-heavy app seems to show 5-10% less time
spent in seccomp call
