Create Android.mk file and a wrapper header for use by CTS.

This re-lands 60aa1eedc716d2c51273a6f6b581500879292870, but excludes compiling
the code on mips and mips64, since Seccomp is not supported on those
architectures.

In addition, several warnings are suppressed.

Test: lunch aosp_mips-eng
Test: m external_seccomp_tests
