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.
