Build native coverage variant of APEXes when needed
When the native coverage is enabled, APEXes (and files there) are built
for native coverage as well.
Bug: 138952487
Test: make -j NATIVE_COVERAGE=true COVERAGE_PATHS='*' com.android.resolv
find out -name "*.gcno" | grep DnsResolver shows files
Test: libnetd_resolv.zip is found under
$(TARGET_OUT)/apex/com.android.resolv/lib directory
