Enable coverage for vendor-related libraries

Bug: http://b/116873221

Enable coverage for libraries that use VNDK and those that have vendor
variants.  This previously caused a redefinition error in the
Android-<product>.mk but was indirectly fixed when
https://android-review.googlesource.com/c/platform/build/soong/+/906394
disabled coverage for LLNDK stub libraries.

Test: m NATIVE_COVERAGE=true COVERAGE_PATHS=frameworks nothing
