Support all architectures in seccomp
Test: Make sure arm, x86, x86_64, mips, mips64 emulators boot
Make sure sailfish still boots
Ran CTS test from
https://android-review.googlesource.com/#/c/348671/3 and it passed
The instructions for how to run mips emulators above worked, but
the CTS tests did not seem to actually run.
