Add data_native_bins property to java_test_host

When multiple os/arch variants are supported, java_test_host could not
find a matching arch due to java having arch:common, whereas native
binaries support a specific architecture. This change adds the property
`data_native_bins` in order to support binaries with the appropriate
os/arch variants.

Test: m FirmwareDtboVerification with data_native_bins
Test: forrest
