Convert to Android.bp

See build/soong/README.md for more information.

I tested the following tests on a Nexus9 and linux host, and they
continued to pass:

/data/nativetest{,64}/bootstat_tests/bootstat_tests
out/host/linux-x86/bin/nativetest{,64}/bootstat_tests/bootstat_tests
/data/nativetest64/memunreachable_test/memunreachable_test
out/host/linux-x86/bin/nativetest{,64}/memunreachable_test/memunreachable_test

These continue to fail just like before this change:

/data/nativetest{,64}/sync_test/sync_test (was /system/bin/sync_test)
/data/nativetest{,64}/sync-unit-test/sync-unit-test
/data/nativetest/memunreachable_test/memunreachable_test

Test: See above
